[Humor! Sokka is almost inclined to like Sans a tiny bit, hearing that. He appreciates banter and enjoys making jokes of his own; he'd be open to making one right now, if it weren't for the fact that he feels like he has to hold Sans' hand throughout what comes next.]

You thought I was dangerous but didn't grab anything to protect yourself with? [It's possible Sans can bend, but given their conversation about colors, Sokka doubts it. Thankfully, Sokka has experience training children, so he isn't exasperated — just disappointed that his (cellmate? fellow kidnapee?) doesn't seem to have any experience in defense.] Take that. [He uses the boomerang to point to a lamp. It's better than nothing, and if this guy turns out to be more than he seems, Sokka can easily defend himself against ugly furniture.] I'm not worried about the door. I'm worried about who's behind it.

[If this is a prison or trap of some kind, the door and windows won't be the only obstacles in their way.]
