It doesn't seem like a situation that would appeal to either Peter/Felicia or Peter/MJ fans. Felicia is again being used to make MJ feel hurt/jealous, and MJ, who is pretty much confirmed as remembering the original timeline, has "Swinging Single Pete" rubbed in her face again. I guess this is the drama TPTB thought the book needed, but I'm just thinking, man, this sucks for everyone.
