Yeah, I hope they land in another book soon, since it looks like they're not going to be a part of USAvengers.
I don't think a casual hook-up between Iceman and Daken would really work, either, as I'm not sure it would fit Daken's character. Daken's obviously not opposed to casual hook-ups, but I think for someone like Iceman, he'd only do it as part of some kind of plan. He'd be manipulating and using Iceman in order to accomplish something else. Not necessarily any big plan, but something that would entertain him.
I'm hoping we get to see him be terrible at dating men, too. Because Iceman is just terrible at dating.
My "solution" to the Kyle Jinadu "problem" is to have him become an X-Men supporting character. The X-Men used to have human supporting characters. Stevie Hunter, Candy Southern, that cop Archangel hooked up with, Opal Tanaka, Lee Forrester, Tom and Sharon, and others here and there. Human supporting characters were a thing. So, why not let that be a thing again? And why not let Kyle be a supporting character for the franchise? He's married to Northstar, but there's no reason why he can't do **** that has nothing to do with Northstar. So give him a job helping the X-Men in a mundane manner and being friends with some of them.
