Using my patented bullshit translator - Loeb is saying something along the lines of "I haven't got a clue where this story is going, I'll be throwing in a lot of twists which are at best random and often nonsensical - not to mention that no one is going to bother checking continuity, so expect plot aspects to be raised and dropped arbitrarily. Red She-Hulk is just going to be cheese cake for the sake of it - any chance at character development is pretty small."
I'd say there's a pretty high probability that there will be a snippet of dialog similar to:
Rulk: You?
She Rulk: Surprised to see me?
Rulk: It messes up all our planning for you to show up! It may even provide an obscure clue to my identity, but oh well. Think I'll beat up... oh I don't know, the Thing.
The possibility that it may be Domino is really really exciting for me, I can't quite say why. Maybe it would be the brains/brawn dynamic, or that one of Liefield's "characters" is going to be bastardized long after her shelf date. Or maybe that the Marvel U can stand to have a few more TF'ing heroines, and that if done properly She Rulk could be a better compliment to She Hulk that Titania. One can only hope.
