Leo's POV:
We've arrived to the lair and put the girl on the table in Donnie's lab. Donnie fix her wound and said, "There we go. She'll be fine, we just have to wait for her to wake up." He said, before getting all the things he needs to free Karai.

Dawn's POV:
Oh, man, what hit me? I try to open my eyes, but the light was hurting me. I blink a couple of times until my vision was clear, I look at my arm and saw that it's all bandaged up.

I look around and found out that I'm in Donnie's lab, "What the heck?" I said to myself, I look and saw the door is open and heard argument.

I slowly and carefully got off of the table, and walk towards it, I look outside and saw Leo, Raph, Donnie, and Mikey arguing. I widen my eyes as I realized that I'm in 'The Fourfold Trap' episode!

I stood here as I watch them arguing until Mikey saw me, thank you for finally notice me standing here. "Hey dudes, she's awake!" He ran towards me and said happily, "Hi, I'm Michelangelo, but you can call me Mikey!"

Leo, Raph, and Donnie aren't far behind him and Leo said, "I'm Leonardo or Leo for short. What's your name?" "My name's Dawn." "My name's Donatello or Donnie. And you mean like the dawn of the sky before the sunrise?" Donnie said, "Yeah, you can say that." "And the ugly one over here is Raph! Ow!" Mikey yelled when Raph hit him behind his head, "It's short for Raphael." He said with his arms crossed as usual and a smirk.

I heard Donnie's T-Phone ringing, Donnie went to grab the phone, and answer it, "Hey April, um not the best time." Oh no, that's Karai using April"s voice to call him! I don't know how Baxter hacked into their T-phones, but I have to warn them.

"What is the problem here?" We turned and saw Master Splinter, "I see our guest is awake." He said, "Oh yeah. Sensei, this is Dawn, she came from another dimension." Leo introduced me. Master Splinter walk towards me and I bow in respect.

"I sense that she has a good soul, she may be helpful to us." He said. "You should've seen her fight, Sensei. She fought against the Kraang droids and she has her own weapon, she can fight but that is until she got hit by a Kraang droid." Mikey said.

Master Splinter stroke his beard and said, "Its seems that she know ninjitsu but not all of it, is that correct?" "Yes. My Dad just teaches me the basic ninjitsu, but not the whole thing because he has a job as a vice principal in another school in my world, so he barely have time to teach me." I said.

"If you like, I can teach you ninjitsu since your father can't." I smiled at him and said, "I would love that." "I'm heading out, April needs me." Donnie said as he left, uh-oh, he's heading to a trap!

"Your needed here now Donnie." Leo said, Donnie ignore him and he left. "Donnie!" Leo yells as Donnie was gone. "My sons, you can not drive each other apart. In time like this, the unite is important. Do not forget the most basic lesson; an effected team thinks as one."

"But what about Dawn? We have to take her back to her world, her family will be worried about her." "And how exactly are you guys suppose to get me home? You don't even have a portal." I pointed out, "I know that. But we'll figure out and get you home, Dawn." Leo said.

"But until then, you have to tell us which dimension you came from." Raph said, "Well, it's kinda a long story, and you guys might think I'm crazy." I said while playing with my fingers, "Just tell us, we promise we won't laugh, right guys?" Leo said as he look at them with a serious look.

"Yup/Sure" they said, "Well, OK." Then I told them that they're actually a TV show in my world and I got into an argument with Luis, and the Kraang Portal appeared in my room, and they know the rest.

After I'm finished telling them, they look shocked and surprised. "Whoa, we're in a TV show?! Awesome!" Mikey said excitedly. "That explains why you didn't freak out when you saw us." Raph said, "I didn't know we're in a TV show." Leo said.

"Well, now you do. And that was Karai calling Donnie as April's voice! Stockman somehow hacked into your T-Phones and leading you guys into a trap!" I warned them, "That was Karai?! How come you didn't tell us in the first place?!" Raph yelled, "Because you guys were arguing like little kids when I just woke up minutes ago." I said dryly.

"It doesn't matter, we have to find Donnie and fast." Leo said, "But I think they got him by now." I said. Then, Mikey's phone rang, he grabbed it and answers, "Um, D, what up dude, where you been?" he ask nervously, we can't hear anything from his T-phone and Mikey said, "Um, I don't know Donnie, I don't think our new friend would like that."

"May I see that Mikey?" I ask, Mikey give me his T-Phone, and I said, "Listen Karai, don't even think about trying to get Leo, Raph, and Mikey into your little trap. You may have fooled Donnie, but I was able to warn them before they were fooled by your tricks, so you better let Donnie go or else." I hung up and give the T-Phone back to Mikey.

They look at me shock and I said, "What?" They shook their heads and Leo said, "Nothing." Master Splinter look at my necklace and he said, "Dawn, may I see your necklace?" "Um, sure." I took off my necklace and gave it to him, he look at it and give it back to me.

"I know I have seen this before." He said as I put my necklace back on. He lead us into the Dojo and took out a scroll. "What is it, Sensei?" Leo ask, "The necklace around Dawn's neck is not an ordinary necklace, its an ancient Japanese necklace called the Changeling necklace, once the person wears it, they can take a form of another person and gains power from the ones the another person and gives it to the wearer themself and to the people the wearer knows."

"I'm wearing the Changeling necklace?" I said in shock, "Dawn, where did you get that?" Leo ask, "My dad give it to me when I was a little, back in my world." "You can not let it fall into the wrong hands, Dawn. Or else it will be disaster." Master Splinter said.

"But what does the person who wears it look like?" Leo ask. Master Splinter showed us and it looks like that one the left side the picture shows a person have wings on his back and his piece of his hair is on his face, and on the right side is also a picture of a woman who also have wings and her whole hair is waving like a gentle ocean wave, and it looks like they both have the same eyes but different eye color, their eyes look like Nightmare Moon or Queen Chrysalis from MLP.

"So all Dawn has to do is to control the necklace and she'll look like that?" Leo said, "Yes, she must learn to control it." Splinter said, "Hey guys. Guys?" We heard April outside and we went out of the dojo to see her.

"Hey April." "Oh, who's your new friend?" "April meet Dawn, she came from another dimension." "Another dimension?" April ask confused. I explain everything and after I'm finished, April said, "Wow. That's sound cool. And its a good thing I went shopping too, because I got something for Dawn. Come on, Dawn."

I followed her into her old room and tried on an ninjitsu uniform and my dagger belt is around my waist.

(A/N: Pretend the mask is on the dagger belt and the ribbons are blue instead red.)

We came out and show Leo, Raph, and Mikey, "Wow Dawn, you look awesome!" Mikey said, "Nice." Raph said, and Leo just stare at me and... blushed? OK, not expecting that.

"Thanks guys, and thanks April." "No problem." Then, Leo's phone rang and saw a text from Donnie which it's Karai. "It's Karai. She said that she want us to met her at the old abandoned warehouse. We better go."

"I'll come too." I said, "No Dawn, you have to stay here, you need to learn to control that necklace." "But... (sigh) fine, but don't blame me when you guys get captured." I said before they left.

Few minutes passed and I still can't work it, maybe Master Splinter is just making it up..... No! No, Dawn why are thinking of that? Master Splinter wouldn't do that, I just need to concentrate harder.

Then Master Splinter ran out of the Dojo and said, "Dawn, you must stay here." "What's wrong?" I ask worried, "It's April and the boys, they are in trouble." "Be careful." I said, he nodded and left.

I concentrate harder and I feel it glowing. I feel my hair waving like a gentle ocean wave like Princess Celestia from MLP and I feel pain on my back and wings appeared, and the last transformation is my eyes, they snapped open as they change into Nightmare Moon's eyes, only a little different.

After the transformation, I look in the water and saw that my wings looked like Nightmare Moon's wings. I grab my mask from my belt, put it on and head where Master Splinter, April and the turtles are, I just hope I'm not too late.
