He wanted to smack all three of them upside the head, and would have too if the....Nightkin? Well, now, this was unexpected. He blinked in surprise at the towering gray-blue hulk in stepping out of the elevator, and continued to stare as it rather casualy nudged aside the NCR boy and reached down to pick up the grenade.

Well, it was usualy just best to play along with their crazy until they got bored and moved away, if you were lucky. Otherwise gunplay was about the only option.
