Which season 8 episode, other than My Absence, is Zach Braff not going to be in?

Zach's already not been in My Absence this season, but I really want to know what the other episode is going to be. Does anyone know?
I think it might be Their Story II as he won't need to be in it, but I'm not sure. (It may sound like I just answered my own question, but I just want to know if it's definite. Also, I wanted to be the first person to ask a سوال on here. :D)


EDIT: I've just found out it can't be Their Story II without Zach Braff. This press release :link says he's in it.
