Twitch on SYTYCD

Okay, I am probably one of the only people in the world who didn't know this but Twitch from "So You Think You Can Dance?" is on Hairspray! I was so surprised! And he isn't just in it a little, he is in it A LOT. First time you see him is in the detention scene, he is also in the platter party scene, the protest scene, the part where they rescue Tracy and Penny from Penny's house, and the scene where they sneak Tracy into the hairspray pagent. He is also the boy at the end where Britney Snow's character learns how to dance. Some people dislike the fact that he is able to be on the show with Adam Schankman (who choreographed Hairspray) being a guest judge, while Debbie Allen (who helped train Will) wasn't allowed to be. I do not have this problem. If that was the case Mia Michaels, Tyce Diorio, and most of the guest judges wouldn't be able to judge because they have worked with/choreographed many of the dancers on the show. I do feel that they should have mentioned this on the show. Twitch is one of my favorites but they tend to portray him as strictly a street dancer with no formal training, when obviously he is good enough at what he does to already have paying jobs. I don't like Twitch any less, I love Hairspray and it is fun to see him on there. I just feel it should have been mentioned. What do you think?
