Yes, well, Karsa is a known jerk. Listen to Five.

Okay! So we're going to say they took a human old man because. That won't alert anyone. Which is why this was such a perfect idea.

I love that they're going to good cop/bad cop this poor man. Five is still going to tie him up though, sorry. These people have been a huge nuisance, he's not getting any sympathy from the little guy.
