~~~Sans POV~~~
I sat at my sentry station thinking about what the lady behind the door said. 'I wonder why she said that in the first place? Maybe I could ask her a bit more.' I thought and got up making my way to the Ruins door.

I was halfway there when I noticed the doors start to open. I quickly teleported into the woods and watched, behind a tree, as a human stepped out. It wasnt Frisk either, I had never seen this person before in any of the timelines. I couldn't tell wether this human was male or female.

They wore a navy blue jacket, with the hood strangly similar to mine. They had plaid shorts that reached a little past their knees, they wore shoes that were black and white checkered, and had a weird shirt that had a pic of (Y/F) on it, the shirt was also (F/C) color. They had their jacket unzipped, with their hands in the pockets, and the hood up.

I decided to watch them. They took casual steps like there wasnt a care in the world, and seemed to be.. Humming? I continued to watch and silently follow them. Then they suddenly stopped in front of the stick I would step on.

Then the human crouched and picked up the stick with a hand. They continued walking while twirling the stick in their hand. I just stood there a little taken aback. I sighed and shook my head 'This is one weird kid.' I thought to myself.

I followed them like normal and dissappeared again. They finally stopped in front of the bridge. The humming stopped and they just held the stick in their hand. I walked up to them, getting my whoppee cushion ready.

I stopped behind them and said "H U M A N. D O N T Y O U K N O W H O W T O G R E E T A N E W PA L? T U R N A R O U N D A N D S HA K E M Y H A N D." I said with a deep voice sticking my hand out. To my surprise they turned around. Pulled down their hood revealing a smiling face.

I was once again taken aback but didn't show it. They shook my hand and the whoppee cushion made a loud 'PPFFTT' sound. They started giggling like a maniac. I chuckled and said, "Old whoppee cushion in the hand trick, always funny. I'm sans, sans the skeleton. Your a human right? thats funny. I'm actually supposed to be on the look out for humans buut.." I paused and watched as they slightly widened their eyes fakely. "I'm to lazy to do that." they fake a sigh of relief, "Now my brother, he's a human hunting FANATIC." Their eyes widdened again and their smile dropped slightly. 'Why are they faking their expressions?' I wondered then looked behind them. "I think thats him over there! Go through this gate thingy, he made them to big to stop anyone." I walked passed them and they followed through the gate.

We stopped a little past the gate and I pointed to the rock structure. "quick hide behind those rocks." and they did. I went through the normal dialogue with my brother and he left. I told the kid to come out and they walked over to me. "Your brother seems cool." they said to me, I smiled wider.
"Ya he is, isn't he? Anyways can you do me a favor?" I asked.
"Sure, what is it?"
"Can you show yourself to my brother, It would really make his day, and don't worry he's harmless."
They smiled and nodded.
"Thanks uh.."
"Just call me Seven." they said. 'well that specifies if their male or female.' I thought sarcastically.
"Thanks Seven, i'll meet you up ahead." I walked off in the opposite direction.

Before I could teleport near my brother the little flower fuck showed up. I gave him an annoyed look. "What do you want?" I said menacingly.
"Have you seen a human yet?" he asked. I gave him a confused look.
"Maybe, whats it to you?"
"Don't trust them." I was taken aback.
"What do you mean?" I asked.
"Well they know who 'I' am, plus they talk to themself for some reason."
"Who 'you' are? And why would they talk to themself?"
"I don't know, but did they act weird when you met them?" I just nodded. "Were they wearing a jacket?" I again nodded. "I don't know whats going on but I do know for a fact they weren't wearing thay jacket when they fell. Just be careful smiley trashbag." with that he left.

I thought about what he said then remembered Papyrus. I teleported near him and started talking to him before the kid came. 'Don't worry pap. I'll protect you.' I thought and saw them appear from the corner of my eye.
