Tristan Wilds' people say he is sick and that is the reason he will miss the last four episodes of the show this season. The writers will just say he is on tour and then next season when Tristan is all better he can rejoin the cast. Whenever publicists will not say what the illness is, then you always have to suspect something because, umm, lets say it was Lupus or something like that. They would jump on publicizing that and getting spokesperson gigs and getting a People Magazine cover. All I have to say is that, even if he is sick, Tristan has been in the blind items before. Just sayin'.
