That's actually quite a cute picture. I dunno why, but I can see this Jubilee running around, flapping the cape, going "WAH-BOOLA-BOOLA!". If anything, she's an optimist.
The thing that bothers me about her new vampire status is well...nobody is really doing anything with it. I think Jubilee can be used to explore the supernatural side of the Marvel Universe more. Heck, I got a couple ideas. Maybe she can roll with Morbius, be his sidekick and help him hold on to his humanity. Maybe vampires have their own sub-culture in the Marvel Universe, and Jubilee can explore that, be used as the readers' eyes.
