It's not a silly explanation, it's only you making it sound stupid. Obviously it didn't happen from day to day, they had almost 30 years for that. As you could see in multiple occasions when Kevin turns evil he loses everything, there i nothing old Kevin left in himm when he is normal he is the good old hero. Also, his last mutation doesn't mean necessary mean he could control his mutations anytime from that.

I don't think that whole adoption thing was canon, it was something that the wiki had. Devlin is confirmed to exist, he probably just couldn't be fit into the story, since he was not needed in the episode.
