If you're like me, you've been cautiously excited about all the new X-Men: Days of Future Past footage, but with one caveat: How the hell is young Charles Xavier walking around when a bullet severed his spine at the end of First Class? We finally have the answer.

As this new clip reveals, Chuck is taking some kind of gene therapy that allows him to walk, but at the expense of his telekinetic powers. Whew! This was driving me crraaaaaaazzzyyy. The rest of the clip, where Charles and Magneto have their little lover's quarrel and Magneto reveals that you probably shouldn't make him mad while you're riding on an airplane with him is pretty good too.
