I totally agree with you about Season 4....I thought of all the show's season, that one was the worst. And I loved how the finale was about the "team" and not just about one particular character....everyone got their spots and moments and it ended with all (except H, Frank and Eric) of them in the same position. I think what started the change reaction with whatever it was that made them all pass out definately had to do with Ryan putting that solution on the stamps....the chemical reaction probably released whatever it was that caused them all pass out b/c if it was the in the air filtration system of the lab then it wouldn't have dissapated by the time Eric entered and he would have passed out too. Gonna be a long summer! lol btw do we know who is under contract to return and whose contract expired at the end of this season? And if so, do we know if anyone re-signed with the show?
