Soooo our Upfronts experience was kind of a bust because (although we didn't realize it at the time) Effy and I got there after all the Glee folks had already gone into the press tent thing. We watched a stream of celebrities who were not Glee people (although some of them were kind of cool like Kevin Bacon and Troy Aikman and Orlando Jones) arrive and go inside but didn't get close to any of them.
THEN when we had given up and were leaving we passed by the other end of the tent where some people were gathering and saw Lea, Jenna, Matt, Jane, Chris, Kevin, and Darren exiting the press tent to walk down the little path to the afterparty. Darren was nice enough to take pictures with a few people right by the exit and when another bunch of girls pressed him for the same he said "Walk with me!" and they started following him down the path. We joined in with this group but he scampered off before we could get pics with him (citing that he was "going to get in trouble with the bosses" although a can't imagine a scenario in which making fans happy is a punishable offense).
Yes, scampered is the right word.
Yes, he's totally short. But definitely better looking in person.
