While Jubilee and X-23 had met before (I believe in the X-23 one-shot from earlier in 2011), this is where their friendship starts. She is on 6 pages of issue 10. Then in issues 11 and 12, she’s on 15 pages each. Significant appearance and a good spotlight on her. Not so significant as a New Warriors appearance but definitely important to Jubilee. Wolverine and Gambit appear as well, but the focus is definitely on X-23 and Jubilee.
We find out that she’s left the mutant island of Utopia. Apparently, Professor X’s attempts on her birthday didn’t quite do it.
Wolverine is still helping her by providing her his blood. Gambit had called Wolverine to help with X-23 in Paris, and Jubilee came along, so it seems like she’s still reliant on the healing factor in his blood to suppress the vampire urges.
I think this is the first time we see her get a flash of someone’s past by tasting their blood, which she does with X-23.
