005 - Curioser and curioser

[ Kara's expression is a mix of confused and concerned. Have you heard the tapping? Because she has. And she totally just spent five minutes talking to a wall. She speaks quickly but clearly. ]

I know everyone's upset after whatever happened that I was asleep for, but I need help. There's, Rao, there's somebody in the walls. [ She is well aware of how crazy this sounds. ] I don't know who or how or why, but it's somebody who knows me. And they might be in pain, and they might be between the walls, but my x-ray vision isn't working on it so I can't tell. I could punch through the wall, but I don't know where this person is, or if it might hurt them...

Is there anyone missing? Anyone who wouldn't have just gone home or something?
