I loved Husk & Jono the whole Gen X crew, i feel that for some very odd reason the Marvel X writers choose to forget Gen X ever happened. They Focus on the New Mutants & then the Academy X kids. Even now Jason Aaron seems to be focusing on the kids that Grant Morrison brought into the school but all the Gen X characters are pissed on and lost in the wind. oh well

The X-Force Apocalypse story has already stated and no Chmaber, Jono, whatever
Since he IS in Age of X I'm hoping that means he'll show back up in "normal" X-books
He's always been one of my favorite characters and I kinda miss him...existing
Although Chamber is much, much cooler than Decible

From what I remember, the last time the whole Husk/Chamber relationship was addressed was waaay back in the early 2000's, around the time of the Trial of Juggernaut arc, when the whole Husk/Angel thing was growing. He walks in on them hugging (gasp!), throws a fit and storms off. Paige pursues him, and they start to fight...while in the middle of assisting the rest of the x-men in repelling Alpha Flight. Husk ended up saying something along the lines of 'why couldn't you have loved me the way I loved you?', which summed it up pretty succinctly. I'm told there was an issue shortly after that where Jono decides to go off with...some group, somewhere, I forget if it's Mutants Sans Frontiers or something else, and Paige asks if it's because of her and Angel, but I never managed to find that scene. 
As to why they never called one another, I'd like to draw your attention to the Poptopia arc, in which Jono goes off and gets laid. By a celebrity. What's more, this happened in England, where there's a considerably bigger tabloid industry (ever wondered why we used to see so many pictures of Amy Winehouse?). It doesn't help that Husk mentions she heard about the whole event when they see one another again, after Jono returns to the US and they meet up again. If this doesn't display Jono's lack of a meaningful connection with Husk, I'm not sure what it does display. 
 
Me, I'm hoping that Husk and Jono never, ever see each other again, because it seems inevitable that should their paths cross, there will be some godawful rekindling of their formulaic and unconvincing relationship. They have nothing in common!

Methinks the current writer/s don't much like Husk. Shame, I kinda warmed up to her. 
As for the whole Paige/Jono thing, part of me says it's the only logical conclusion (at least a one-night stand!). The other part is pissed at Jono for being such a whiny little emo jerk for like every issue he's been in, ever. I'm just hoping he's grown up since I saw him last; his gloomy angsty crap was almost rivalling Wither's...

Chamber's one of my favourite characters, I really want him back too.
