I honestly think she'll be raped. I don't mean to be so blunt, but what other way is there to say it? And ideally, she'll run away and Magneto will come to Charles to find her using Cerebro. So, Erik, Hank and Charles rebuild Cerebro in order to track down Raven. I doubt Charles would actually tell Erik when he realizes what's happened to his "sister". She winds up needing Charles and Hank to deliver the baby because she's unable to go to a hospital. I wouldn't be surprised if she's the whole reason Erik and Charles fight; because Erik's not willing to abandon the monster that did such an awful thing. It sheds a new and not-so-positive light on Erik. I think Mystique would probably give Kurt directly to a family that would be able to properly care for him; leave him at the traveling circus that's in town. Reason for giving him up? She doesn't want Kurt to be molded and manipulated by Erik's preaching.
Anyway, 'just my idea. I mean, in the comics Azazel essentially conned her into it because she believed he was someone else completely.
