Well - you have to hand it to Stacy, she knows her Greg, and she is exactly right about how the first scenario would go. It breaks my heart that she felt she had to leave anyway but I can't fault her reasoning - this event just crystallises the problems she had with their relationship already. I do wonder what happens to House now - does he go down the same path as before, or follow a different one?

Fascinating little story - I love these sorts of alternative paths for canon events!
