Rude looks right back at Tseng when he sees that familiar expression on the man's face. He's thinking of something he shouldn't. Something that tickles him, and whatever tickles Tseng would make most men want to vomit or shit themselves in fear. It would truthfully be a reasonable response, not as reasonable as turning around and getting as far away from Tseng as possible.

Unfortunately Rude doesn't have that luxury, and even if he did, he's not afraid of Tseng or his peculiar tendencies. He's heard whispers, and doesn't doubt them, but he's never done anything too out of line to Rude. Although he's not a fair judge considering they've all threatened each other with violence before a handful of times. Elena is trigger-happy, Rude is Emotional, Reno doesn't hold back, and Tseng might actually be a sociopath. Of course they fought.

So, Rude sighs as he removes his gun from the holster, screwing on the silencer before firing a warning shot right into the wall behind Tseng's head.

"Give me your phone and get on the damn couch." All of Tseng's words were just words. Being behind schedule wouldn't last knowing how hard they all worked. It wasn't an excuse to not sleep. "You make mistakes when you're tired. You start to behave strangely. Let everyone else worry about our enemies, and get some sleep."
