Ultimate X-Men #58A

A Hard Lesson
The X-Men are in New Jersey dealing with Warlock while the Professor tries to determine why all of his assets are frozen. It seems the Hellfire Club is attacking him financially now, but before he can clear that up, the mutants known as Syndicate burst in to the bank in order to rob it. The Professor uses the resources at his disposal, including all of the other hostages, in order to get everybody out in one piece.
