Re: Where has Scott Summers gone?
I suggest you re-watch the entire infirmary scene. Logan asked Jean a few times about what happened to Scott. She didn't say specifically that she killed him, plus we didn't see anything in her flashback that implied Scott was killed.
and, it was only Xavier who threw it in her face about not controlling her powers and killing the man she loved. Xavier did sense something had happened at Alkali Lake but it was just a disturbance (like a disturbance in the 'force'). My only conclusion, that he only felt the disturbance briefly and when Logan and Storm bursted into his office, he told them to go to the Lake.
Did anyone know when Scott left the mansion, know he was going to Alkali Lake?
