@hopesummersforthefuture: 1) Circumstances where a person would accept a cheating partners implication of thinking of them while having sexual with someone else:
•Desperation- The person is so scared of being alone or being humiliated publicly that they stay with their partner begrudgingly. Considering Jean was as ok as a person could be with news of what happened between Scott and Emma, this is unlikely. Jean also has plenty of admirers to rebound on if loneliness were the culprit so she has no reason for any desperation.
•Yandere- Ok, I’m using a Japanese trope, but for those who don’t know, a yandere is a lovesick person, obsessed with the object of their affection so much they’d do anything to be with that loved one, going so far as to underhanded things, manipulation, or even murder. Jean has every opportunity to this day to kill Emma, Force Scott’s thoughts, and get away with it with no one being the wiser. That wasn’t the case lorewise, so that’s out.
•Stupidity- Plain and Simple. Jean’s mama didn’t raise no fool, so the likelihood of this taking place is at 0%.
2) Marvel confirmed sometime before Issue 8 of Jean Grey’s solo that the relationship of Scott and Jean was all but confirmed publicly to be over. That should give you a clear indication of who Scott chose in his heart before Jean died. Nice try.
