What on earth are you on about, he's exposing Siavash as the fraud he is. For pretending to be out of the game, fiddling noms, wanting everyone up because he's a coward, etc.
You are so so biased. It's Siavash who is desperate to talk about noms, and EVERYONE has known that for weeks. It's his perogative.
Charlie exposes Vash for being a faker, but we already knew Vash was a faker.
