Feldspar is trying to sneak around a huge mansion/palace/whatever to steal a treasured item, only to be caught by security (Christophe and Tweek). In exchange for them not giving up Feldspar's presence and getting him arrested, they come up with an EXTREMELY satisfying compromise (Extra bonus points if it's called Blow Your Cover cause you know)
