You were suddenly transported to Judgment Hall. You're here from different AUs.

You appear in Judgment Hall, and you fall on the ground. You see 2 skeletons and a human in front of you. One tall and the other short, the human being more in between in height. Here the same way. The short one grabs you by the collar and raises into the air

Sans: Give me one reason I shouldn't kill ya!

Papyrus: Hey, shortstack! Put them down! None of us know why we're here.

Chara: Drop them already, there’s no point killing them when they aren’t even the human.
