Luna takes Sans, Papyrus, and Frisk, back to the castle after showing the three around Ponyville. Luna smiles as the pegasus carefully lands the cottage down on the ground. They all got out of the cottage and made their way inside the castle. Frisk smiles as she gave a big yawn before she felt Papyrus' bony hand picking her up and carry her in his arms.

"Good night everyone," said Frisk as she began to fall asleep in Papyrus' chest.

Sans chuckles as he looks at Frisk, "night kiddo, tomorrow is another day to explore Equestria especially since tomorrow we'll be going with Celestia to the Crystal Empire to meet Princess Cadence, her husband uh..."

"Shining Armor" intervene Luna making sure Sans knows.

Papyrus said liking the name, "wowie, he must be a royal guard!"

Luna giggles, "he is actually even before he marries Cadence he was destined to be the royal guard. He was Celestia's guard for two years before he went to the Crystal Empire to be the royal guard for Cadence."

Sans chuckles, "cool, he sounds like a good husband to Cadence and a good father to Flurry Heart."

Luna nods, "Oh yes, they are indeed a very happy family."

Papyrus yawns as he said goodnight to the two and takes Frisk to her room and tucks her to bed. Once so he went to his room and lay on the bed to sleep.

"You better get some rest, Sans," said Luna as she sees him coming close to falling asleep.

Sans nods, "I better before I stand and sleep here" he chuckles and went to his room to join Papyrus, "night Paps, see ya in the morning."

With that everyone slept as Luna went to the dream realm to see if any pony is having nightmares she has to help them overcome or fix.

Twenty minutes later, Luna came out of the door leading to Starlight Glimmer's dream and sighs, "that was... different good thing it wasn't the one about my sister turning into evil like I once did."

Just as Luna was about to walk out of the dream realm she saw Sans' dream door appear in front of her, "what's this?"

She came up closer and saw that the door was half open easy for her to go into, "this doesn't look good if Sans' dream door appears out of nowhere. Let's see what kind of nightmare Sans is having."

Luna walks in when she found herself in another place that she really doesn't remember being in. She saw the yellow tile floor is shiny and the large yellow pillars all clean as well. The sunlight beaming through the window of the hall.

"W... where am I? I do not recall being here before? Is this where Sans was in the Underground before Frisk fell and help them return to the surface?"

Suddenly Luna heard footsteps not too far from where she was. Luna was about to go and see whose footsteps she is hearing but suddenly she couldn't get any closer with some kind of invisible force was trapping her to stay between the two pillars. All she could do is to watch and see where this dream is going.

Suddenly the footsteps stop as Luna turn to see Sans standing in the middle of the hall wearing his same old clothing only... Sans seems to have Papyrus' red scarf around his neck. Sans looks towards someone that Luna heard the footsteps from and sighs.

"Heya, you've been busy huh?"

"Sans?" Luna was confused but she couldn't do anything but see what is going to happen next.

"So uh... I've got a question for ya. Do you really think that the worse person could change if they just try?"

Sans pretend to chuckle as he continues to speak.

"Okay here's a better question, do you want to have a bad time? Cause if you take a step closer your not really going to like what happens next."

Luna heard the someone take one step closer towards Sans.

Sans shakes his head and sighs once again, "whelp, sorry old lady this is why I never make any promises. It's a beautiful day outside, birds are singing, flowers are blooming, on days like these, kids like you..."

Sans' right pupil began to glow as flames began to flow out of that blue pupil and his voice deepen very scarily, "Should Be Burning In Hell!!"

Suddenly Sans made multiple bones appear and aim straight ahead. As well using the large animal shape skeletal heads to blast.

Luna finally saw who Sans is attacking and saw Chara grinning wide with a knife in his hands. Luna's eyes widened as she could not understand what's going on.

"Funny you should say that," said Chara as his form turns into Frisk's form still having the red eyes, "you should burn in hell especially after what you did to Frisk, I mean you kill her for no reason when I was the one in control. Yet, you kill her over, and over, and over, and over, again. It was like you really enjoy hurting us."

Sans stops as he looks at Chara, "you know I never..."

"Sure" interrupts Chara, "you never knew it was her till I show myself to you. Yet even if I never had show myself or prove I'm the one to kill everyone before, you were so happy when you killed Frisk. I even let her choose to show Mercy to you but... you refuse her Mercy and kill her like this."

A large white bone went through Frisk's body as Chara appear behind Frisk. Frisk looks at Sans with tears streaming down her face blood splatting all over the floor.

"Why? Why did you do this to me, Sans? I didn't do anything I just want to see I'm not the bad kid."

Sans shakes his head as he stood in shock, "n... no... this can't be..."

"Oh but it is," said Chara, "and you know what you did and Frisk was only eight years old she was just a child. However you didn't show any sympathy or pity for her at all, you just killed her just like that. Here everyone or pony think Luna was all bad being Nightmare Moon but... who's the real villain here? You are!"

Sans started to cry and place his bony hand over his head. Suddenly Chara appears before Sans and uses his knife to slash the skeleton causing him to fall on the floor bleeding.

"No!" Luna tries to break free but she couldn't since she couldn't get close to Sans or the visionary image of Chara from Sans' dream.

Suddenly Luna found herself back in the dream realm as she sighs, "he must have woken up I should check on him and see what's going on."

Luna made her way back to the castle as she flew to see Sans sitting down on the bottom step of the stairs.

"Sans, may I ask you something?"

Sans nods as he saw Luna sitting next to him. Sans could see Luna was serious about something though he didn't know what.

"What is it you need to ask?"

Luna glares at Sans saying, "why didn't you tell me?"

Sans was confused since he didn't see Luna in his dream, "tell you what? Why I can't sleep that's pretty obvious just had a bit of..."

"I know Sans, I was there to see it."

Sans looks at Luna, "wait... what?"

"Why didn't you tell me what you did?! I know you were upset that your brother was killed from the previous timeline. But why didn't you tell me about your mistake in killing Frisk?"

Sans eye sockets widened in shock. He forgot that Luna has the power to go into any pony in his state any skeleton's dreams.

"I uh... um... guess didn't know it wasn't her making the genocide. I really couldn't see Chara till uh... who the hell knows how long that Genocide was going."

Luna kept her serious face, "I thought we both agree we would share our mistakes secrets with each other. I told you mine but you... you never did."

Sans gulps, "Luna, I uh... I'm sorry but..."

"But what Sans?! Do you think I was a fool to not find out your secret?! The only time I do find out is when I enter into your dreams?!"

Sans sighs, "hey no hard feeling kay? I had to keep it from you because... I didn't know how you would react if you found out."

Luna was upset at Sans but keep her voice low, "does Frisk knows what you did to her?"

Sans nods, "sadly yeah, but she did forgive me since yeah... I didn't know it was Chara."

Luna looks down as she kept silence.

"Look" continue Sans, "I'm sorry okay? I just... didn't know what to tell ya about this and uh... guess I didn't think you needed to know?"

Luna narrows her eyes, "how could you?! I would have help you try to ease your pain with the past but you choose to refuse my help!"

Flew off towards her room.

"Luna!" Sans sighs hearing Luna shutting the door of her room, "nice going Sans, you blew it cause you were so damn afraid to say anything and like she said she would have help in some way. Now she probably won't talk to me ever again."

Sans stay where he was as he felt bad for what he did and try to find a way to save his and Luna's relationship. Maybe he should have Frisk help him tomorrow with this situation and won't cause Luna to break up with him.

"I can tell tomorrow is going to be a living hell for me."

The next day, Sans went into Frisk's room and sits next to Frisk on the bed, "hey, uh... can you help me with something?"

Frisk nods, "sure what is it?"

Sans sighs, "it's about Luna, she got in my dream and found out about the timelines and me killing you and stuff."

Frisk lower her head, "oh... she did huh? So what happened?"

Sans explains what happened last night. Once he finishes he sees Frisk was nodding her head and thought a minute.

"Hm... maybe tonight I'll join you to see if we can't get Luna to come around."

Sans sighs and pets Frisk's head, "I knew I could count on you."

Frisk nods, "anytime Uncle Sans, let's get downstairs so we can have breakfast and meet Cadence and her family at Crystal Empire."

Sans chuckles a little, "alright sure" he follows Frisk out of the room but he couldn't get his mind off of what happens between him and Luna, "I hope Frisk will help me get Luna back and not cause us to break up."

They made it downstairs and met Celestia and Papyrus waiting for them.

AN: Yay, I got this one done! Eh... finally got the time to do this chapter. So part 2 of The Talk and things are looking a bit heated right now. We'll see what is going to happen next. I'm planning to have four parts hopefully unless I have to add one more part to make it five. We'll see...
