Hell, the lack of interaction between Magnus and important people of his "X-Men period" really annoys me. We barely see him talk with his former students. Not even Illyana or Doug (remember how hard his death affected him?)
I sometimes remember how Colossus was pratically a nurse to Mags when he was comatose post-Fatal-Attractions and now they don't seem to know each other.
Just hope we don't have to wait 50 years like we had to see him and Polaris develop a relationship lol.
