I think you've hit a very important point about Clark. With his higher obligations, he can't always be around, even though he would want to be. He needs a strong woman. And Mayson, along with her dislike of Superman, isn't strong in that respect.

Quote
Mayson said that she loved him and that she knew that he cared for her, but that she needed someone who, when the chips were down, would put her first, before everything else in his life – including Superman – and she didn’t think that he could ever do that. She had thought for a few minutes that morning that maybe she could teach him to do that, but he proved to her without a shadow of a doubt that he could not.
Nice to see something good happening for Alt-Clark. I liked the moment between he and Sam when Sam assured him that being upset after someone you cared for was hurt was perfectly normal.
