.. Mary could realize how dumb she was for ending it. And Scott will receive her with open arms
If you go back a post before mine, you can see this was more directed at the comment on Mary more than anything else.
Things might be good when they are together, they might not, we don't know. That's their bag anyway.
It is not surprising since both Scott/Mary have discussed their relationship details quite a bit in a various public avenues and forums, people are going to comment on some of it. Commenting on it and making judgments though, are two separate issues.
