I just feel the need to clarify one thing:

IMDb while a great site to find out a lot of things about TV series,
movies actors etc. it is also editable by ordinary people like me and
you.So, until an episode comes out, never trust IMDb.And proof is back
at the 6x08 episode where Jack Plotnick was in the cast list but never
seen in the episode.I don't mean to be a buzz-kill but I see that a lot of you grow hope over this and you are going to be greatly disappointed eventually.
