If issue #1 was about introducing the cast of characters, issue #2 is all about introducing the school itself. As I said, Young has a lot of characters to juggle. In order for this story to take off, he has to plant the seeds of relationship, both good and bad, early on.
Empyre #0: Avengers is a set up issue in a similar vein to other recent #0 issues from recent events. Seeing as this set up probably needed to be done for those readers entering the event cold, Ewing at least made it enjoyable.
