"I do like the idea of Nick Fury, the badass Ultimate version who has taken shit off of no-one, so far, being ordered around and have his ass kicked by his wife, but I just take such an issue in the fact that there's been zero foreshadowing of this. If Millar had this in mind all along and didn't plan it in say, the last six months, we would've at least gotten some decent references to it, like Fury at least asking if his ex was okay during the two finales of Ultimates and Ultimates 2.."
But what if the idea didn't come to him until recently? You say so yourself that its a good idea, but just because it wasn't introduced with the origin of Ult. Nick Fury, it can never be used? If an idea is good, shouldn't it get the chance to be used, even if it refers to a piece of previously-unmentioned backstory in an artform that is based on serial installments?
