That was meant to give Blaine some distinction from the rest of the soilders. True, I didn't think MTV really fit his character much, but he probably didn't know what MTV WAS, which is probably why he was wearing it. Personally, I thought the parts where the guys were talking were some of the movie's strongest moments. Though I must admit, the part where the Pred shows Blaine the REAL "old painless" is my favorite scene. I have to yell "BOOM!" everytime I watch it. Yes, I'm a gore-hound. Leeme alone.
