Ashley, I'm sure Lea and Cory are both professional enough that what goes on off-set shouldn't effect their work. Besides, Jon and Lea have been best friends for years and had simulated sex on a stage in front of a live audience almost every day for 2 years so I'm not really worried if they bring Jesse back next season.
I mean, look at TVD, I'm glad that Ian/Nina's relationship hasn't made the writers decide that DE should be together right now. As much as I would for DE to happen, I wouldn't want it to be b/c Ian/Nina are together.
Nat, I post over there. There are a few of us that post regularly over there pretty regularly.
