In the next day, Elena was walking in the hallway. She knew if Silver finds her now, she will pull her back to her room to rest, but she didn't want that. While she keeps walking, she was noticed by Arcee.

"Elena, shouldn't you be resting?" Arcee asked.

"Would you like to lay down and do nothing if you would have been me?"

"I'm not human."

"Well, I know not to run into any danger," Elena said. In this Arcee sigh. "I'm sorry. I didn't mean to..."

"It's okay. It was Miko who followed Bulkhead through the ground bridge. Silver told us."

"I would be lying if I say this, but I did have a feeling she was going to do that someday, I just didn't expect it so soon."

"Did you?"

"I have been at school too. I have seen teens like her."

Arcee smiled a bit at her. She knew she meant well.

"Were you going somewhere?" Elena asked.

"You know what happened when we all came back."

"You go see Jack." Elena finished. Arcee simply nodded. Even if she wasn't excited about looking after a kid, it still felt like she losing someone. Elena could see it too. I was unconscious when it happened, but she has wondered would she have changed his mind by saying something.

"Can I come along?" Elena asked.

Arcee smiled a bit more before transformed and allowed her to get on her before they left the base.

They drove to KO burger just when Jack was getting there.

"Nice bike," Arcee said getting his attention on them.

"Arcee, really, Miko already tried. Tell Optimus I respect him big time. But if you're at war with the Decepticons, there's nothing I can do to help,"

"Optimus didn't send us and no one's asking for your help,"

"OK. If we both agree that I'm not warrior material,"

"Jack, I just lost someone I cared about. Maybe it's the grief talking. Maybe you're growing on me. Whatever it is, I'm just not ready to say goodbye"

"Besides, you didn't let me say goodbye or anything," Elena said while got up from Arcee.

"Are you going to say it then?" Jack asked.

"Jack, I understand if you don't want this and we won't force you. But think this straight. None of us didn't know this was going to happen. Even I didn't know what was going to happen. But unlike you, I didn't have a choice, but I haven't regretted it, because I knew, that I'm needed. They are not just team. To me, they are my family now and I would do anything to help them."

There was deep silence for a moment. In that Jack was amazed what she just said to him. It didn't sound like asking to come back like Miko tried, but it felt different.

"I need to get my helmet." He said and went to pick it up.

"Was I that good?" Elena asked.

"I was going to ask you the same," Arcee said.

It didn't take long before all three were heading back to the base.

"Elena, What did you mean back then? That you didn't have a choice?" Jack asked.

"Let's just say if it wasn't for them, I wouldn't be alive," Elena said.

Jack didn't dare to ask more. Whatever happened to her, it sounds to be serious to her. She would probably explain it more someday.

Meanwhile, the Autobots have pinpointed Megatron's space bridge in Earth orbit and to get there they must use the GroundBridge to reach it, despite the risks this poses since Groundbridge works limits in on planet Earth, so who knows what will happen. But for Earth's sake, they have to try.

Right when it was decided, Arcee and Elena came back with Jack.

"Hey. Guess who's back," he said.

"Autobots, prepare for departure," Optimus announce.

"Where to?" Arcee asked while transformed back into a robot.

"The final frontier," Miko answered in a mysterious manner.

"Space? I thought they didn't have a way to get there."

"They don't, really," Raf said.

"So, a "leap of faith" for Earth's sake," Elena said, while went to take her place front of Star computer.

"Be seeing you," Jack greeted uncomfortably to Arcee, earning a nod and a smile back.

"Be careful, Bee," Raff begged as Ratchet activated the GroundBridge.

"I'm so jealous!" Miko said to Bulkhead.

"Don't even think about following me," Bulkhead warned his friend.

"We humans don't breath in space, not mention we might freeze up in seconds. She is not that stupid. But we will watch over her." Elena informed while checking the data on Computer.

"Hey!"

"I mean it, missy. You got lucky this time." Elena reminds Miko. Jack tried to hold his smile. Looks like Elena wasn't kidding when she said she is needed. It's like she is next in charge when it comes to humans.

"Optimus, if you leave me stranded on the planet teaming with humans, I will never forgive you," Ratchet threatened Optimus.

"I heard that," Elena said out loud.

"Until we meet again, old friend," Optimus said to Ratchet before he and others passed through ground bridge. Once another side in space, They land on the space bridge terminal and look up to see the Decepticon ship moving into position. The mission was simple nothing comes in or out.

As the Autobots assume attack positions, Arcee notes that the Decepticons haven't done anything. Optimus scans the ship and learns that Bulkhead damaged its interstellar navigation dish during Agent Fowler's rescue. Since a target as far as Cybertron needs pinpoint accuracy, the Decepticons will be unable to use it to aim the space bridge without an alternate targeting system. Well, comparing human technology and Cybertron's it will take a lot of work. That's when Raf reasons that the Decepticons may be using the Giant Sized Array radio telescope in Texas. Now the question is what to do. Agent Fowler could go, but he is still too out of it to alert the array staff to the danger. In fact, in its surprise, he woke up and said something until passed out again. In this, Raf attempts to hack in, but the array's firewalls are too good. And to be honest Elena is that good to hack with Star computer. Sure it can collect knowledge from the internet, but hack into the system can be risky. Star computer wasn't built for that. Not even Silver like the idea. That's when Jack thinks they should go on the site, and they talk Optimus into letting them do it. Optimus and Elena were against it, but Jack and others said reasoned that this is about saving Earth, their home, they have to do something. So, Optimus agrees and so does Elena once she told that Silver goes with them just in case for protection.

While Autobots started to fight with Decepticons, The kids and Silver GroundBridge to the array and sneak in. In a small, unused room, Raf finds a computer and determines that the Decepticons have also hacked in, but takes the opportunity to download their space bridge plans onto his flash drive. Little do the kids know that Soundwave is in the very next room, plugged into the computer system as well. He aligns the array, which sets the space bridge ready to use, but Raf promptly realigns it. Seeing that something is taking long, Starscream contacts Soundwave to know what is going on Responding to Starscream's requests to know what's going on, Soundwave taps into the installation's security systems and locates the three kids and metal wolf. While the kids are discussing what the Decepticons could do, Soundwave's tentacle slithers into the room behind them and attacks. As it goes after Raf, Miko grabs an ax and strikes at it, while Silver tries to protect Raf. She hits the tentacle with a clang, but the tentacle then strikes her backward before picking up the ax itself. Though the kids believe it's about to attack them with the weapon, the tentacle withdraws. The kids run to the next room, where they found Soundwave has realigned the dishes and used the ax to cut the hard line, making it impossible to undo his work. Miko then takes a cell phone photo of Soundwave. Before Soundwave leaves, he takes a photo of them. Once he was gone They realize there's no turning back. It's up to bots now to save the planet.

Meanwhile, in Space Autobots had stood well, even while had noticed Space bridge moving, but what really worried them was, when it got active. It only meant it's all set to Cybertron. Megatron came out with the huge pile of Dark energon, which he throws to the space bridge and the to Cybertron, reawakening all dead cybertronians into zombie terrorcons.

In the base, others could notice the effect, when Ratchet spots lots of signals from undead terrorcons. The effect is already affecting Elena and Silver. For Elena, it was like having a huge headache, while Silver was shivering like she was in Arctic. Optimus realizes that the only course of action left to them is to destroy the space bridge. Luckily, Raf supplies the specs he downloaded earlier.

"Optimus, I must say. The Space Bridge is our sole hope of ever returning to Cybertron. Are you certain its destruction is the only option?" Ratchet asked.

"I am afraid so," Optimus answered gravely.

"Then, by all means, let us light our darkest hour!" Ratchet proclaimed as he sets about working out a way to do so with Raf's help.

As it is settled, Optimus orders Bulkhead, Arcee, and Bumblebee go to implement some sabotage While he faces Megatron to give them time.

While Raf was passing through the blueprints of Space bridge to Ratchet, others could notice Terrorcon signals getting near the bridge. While it was happening, Silver's and Elena's effects were getting worse. Elena could stand up by all the hurt and had to lay down, while Silver's shivers were getting worse as if she was having a stroke.

Megatron manages to defeat Prime, but as he raises his sword, Starscream alerts him to the actions of the other Autobots. Optimus takes advantage of the momentary distraction to block Megatron's killing blow, and blast him away, but the Decepticon leader transforms and flies off to find Prime's team. Arcee's team has succeeded in rigging the space bridge to blow up before Megatron's dead army arrives right when Megatron attacks and blasts her off into space.

The Space bridge started to break into pieces and show signs of the huge blast coming up. Autobots take the chance to leave the place through Groundbridge, while Seeing the potential damage the exploding space bridge would cause Starscream decides to pull the ship back, imploring Megatron to do the same. Overcome with regret over the loss of his army of Terrorcons as they begin to come through, the space bridge explodes in Megatron's face.

Meanwhile, in base, kids, Elena, Silver, Agent Fowler and Ratchet were waiting for the team to arrive. Elena and Silver had got well, since the explosion, but they looked so sad as if they sensed something has happened during the escape.

"Do you think they're...?" Raff asked.

"Four life signals. One very faint," Ratchet read out gravely.

Soon first to come out was Optimus Prime. Seeing him, Elena runs to him without a word as he picks her up to his hand. Then Bulkhead comes and Miko goes to him.

Right then Bumblebee rushes through carrying Arcee to the base. Seeing this Silver rushes to her, whining her to wake up, but nothing happens.

"No..." Elena says low voice.

"We lost one this week. By the AllSpark, don't let it be two,"

Elena tried to hold her tears as she looked on Arcee. She is her friend. No, she is part of her family. She doesn't want to lose another member anymore.

"No...no, don't be..."

She couldn't take much longer and fall on her knees and started to cry. When her first of her tears drop from her face, Silver looks up at her as in sensing something.

Right then, Arcee started to open her optics and saw Jack's worried face. Others started to be relieved to see that they wouldn't lose any other team member.

"Arcee."

"Jack, really? There are other motorcycles in the world," Arcee smirked.

"But you're my first,"

"And Megatron?" Ratchet inquired from Optimus.

"Not even he could have survived Ground Zero,"

"Prime!" Fowler called out, breaking the mood, "I didn't get to thank you bots for the save. I owe you one. We all do." he said before he left.

After that, Bumblebee helped Arcee to stand up by herself. She obviously needs to rest like everyone else. Before that, Miko wanted to ask something.

"Is this the part where you have to say goodbye and tell us to forget we ever saw you?"

Optimus looked on Elena who has calmed down from crying and looked back.

"Well, they got us the blueprints of bridge otherwise, we would have been faced zombie army." Elena remind. In this Optimus nodded.

"So, we can still come here?" Raf asked.

"I don't see no reason why not," Elena said.

"Woohoo!" Miko shouts.

"But we still have the same rules." Elena remind.

"Oh come on!"

"Works for me," Jack said

"me too," Raf said.

In the night time, when kids have gone to their homes. Arcee was passing in the hallway until came to the door, which leads to Prime's quarters. She knocks the door, while she heard the voice of Optimus speaking with someone until it stops by her knocking.

"Come in."

When she entered, Arcee realizes that he was talking with Silver.

"I'm sorry, sir. I wanted to speak with Elena." Arcee said.

"Elena has already gone to sleep. What you wanted to talk about?" Optimus asked.

"Well, you see... this may sound silly, but when I was unconscious I kinda heard her crying."

"Just her crying?"

"Yes. It felt like I was in recharge I couldn't hear anything or be aware what was happening since Megatron hit me, but then suddenly I hear her voice crying for me."

"But you didn't hear anything else. As in when you passed through Groundbridge or Silver whining." Optimus asked. In this Arcee shook her head.

In this Optimus looked on Silver, who nodded.

"It could be that..."

"What is it, sir?" Arcee asked.

"Silver told me that before you woke up, she felt something. Something that came from Elena. At that time she started to cry because of you."

"You think...?"

"I'm not sure. It could be a coincidence. Silver, however, told it could be possible that her Star powers are growing up since she got my energon to recover from dark energon's effects."

"As a Star, she shouldn't stand the presence of dark energon," Arcee remembered.

"It explains why she fainted yesterday when Ratchet and I faced the undead army. But it looks like by getting more energon her powers are getting stronger as well."

In this, Silver whined and looked worried.

"But this is so far guessing. Right now, we have passed through a rough day and we deserve to rest. Especially you, Arcee."

"Yes, sir," Arcee said and was about to leave with Silver.

"Arcee..."

She turned around to face her leader.

"I'm glad you're still with us," Optimus said.

"Likewise, sir," Arcee said and left with Silver.

Once the door was closed, Optimus looked in the direction where Elena's room was connected to his. He then went to his desk and opened one drawer where he picked D-pad, where he usually added his important recordings. Next, to it, there was another D-pad. He looked at it for a while before he closed the drawer and started to record D-pad.

"Without a means of leaving this world, we Autobots take strengths in the bonds we have forged with our three young friends. True warriors. If not in body, then in spirit. My name is Optimus Prime. And I send this message. Though we did not choose to be of Earth, it would seem that we are here to stay. If you approach this planet with hostile intent, know this: we will defend ourselves. We will defend humanity. We will defend our home."
