I guess it really was an expanded role because we did get a little bit more of Jubilee being seen in a classroom and/or standing around, and we get her napping (actually passed out) through a chunk of the film as well. She does get a line to say, but since her name is never said at all and she never uses her powers, how would a novice ever get to know her and love her the way comic fans got to do? She also gets to go to the mall with Cyclops, Jean Grey, and Nightcrawler, but the mall scene itself (complete with a Dazzler reference) got cut from the theatrical release. (Supposedly it and a brief moment where Jubilation uses her powers will be included in the DVD release.)
I know there are a lot of characters in these films already and it is hard to find the screen time to introduce or give quality time to even more, but Jubilee has been in four X-Men films now and has done NOTHING. Why include her at all? (But, please, DO include her from here on out...) Lana Condor, the actress who plays Jubilation Lee, did a fair amount of press and interviews for the film, so it is very surprising that she has been treated so shoddily. Fox also had a chance to spotlight two Asian-American actresses in this film, and totally dropped the ball. (No surprise there.) And I guess it is way too much to hope that Jubilee might eventually team up with Wolverine like they did in the comics for a long run.
Don't even get me started on Psylocke...
