"Greater Love Hath No X-Man ..."
The X-Men battle the original X-Men and don't do too well. Eventually Wolverine uses his enhanced sense of smell to determine they are fakes and they overcome the phonies.
Lang is upset, and when Cyclops breaks out of his containment tube, he tries to escape. Jean uses her telekinesis to make Lang's shuttle crash.
The X-Men have won, but the problem is how to get back to earth, as their Shuttle's shields are damaged and Peter Corbeau certainly would not survive the increased solar flare activity.
Jean decides that she is the only one who can do the job, she telepathically absorbs the knowledge to pilot the shuttle and tries to screen out the radiation with her telekinesis. The other X-Men go into a life support chamber while Jean begins to pilot the shuttle towards Earth. Halfway through the flight, the radiation begins to seep through.
