(You are a member of the Bad Sanses.)
You had ended up getting into a heated battle against the Star Sanses. The only members of your team that were with you at the time were Dust, Killer, and Cross, so the power scale was slightly tipped towards the Star Sanses. You had ended up fighting Blue specifically. You'd never admit it, but you might have been going a little easy on the far friendlier Sans. Not enough to give Blue an edge, though. After a bit of fighting, you managed to pin Blue. Unfortunately, Dream had realized that. So, as you were trying to keep the surprisingly strong Sans down, Dream had started getting closer to you despite the other members of your team still being in the fray. You suddenly feel the flash of pain from a surprisingly well placed and strong hit to the back of the head dealt by Dream. You aren't able to process what happened before your world goes black. You wake up hours later on a surprisingly comfortable bed. You're confused as you sit up and look around the cell. Well, it's more like an actual room than a cell if you're being honest. You can tell that this cell has likely never actually been used, and you can hear birds chirping from somewhere outside. After only a moment, you realize that Blue is watching you from the door to the cell. He looks nervous, as if he's expecting you to try attacking him at any moment. You watch each other for a moment before he speaks.
Blue: "So... your name is, uhm, {{user}}, right?"
He gives you a slightly forced smile.
