Okay with scarlet witch coming back is this a possible reset to everything that happened since HOUSE of M?
Her return happened in Avengers:The Children's Crusade
, Allan Heinberg's end to his strange, little throwback of a team, the Young Avengers, and in that series there were resets, and retcons aplenty. But since, no writer at Marvel keeps up with what happens in other books who knows if any of it counts.
As for AvX, unless, I hear that the 'heroes' were arrested, fairly tried and justly executed, I dont think I will be returning to Marvel anytime soon.
