Wow! I mean this episode was sad. Altought there was some laugh, the majority of it was heartbreaking. I haven't fell like this since the episode "Bed, Bath, and Beyond". I loved it. It was nice to see some of the characters (Ellen, Rob, Larry, Joe, Tina...) again that we didn't see for some time now. I especially loved the scene of Will's mom, Marilyn, and Will talking about George. It was sad. Marilyn was right though, Will is secretive. I mean when a gay man lives his childhood not telling the world that he's gay, I guess sometimes nothing changes even if you come out.
Anyway, seeing Vince again, I think Will definitely needed that. They are great together, and I hope that Will finally let Vince meets his mom, so that they can bond.
The funny parts for me was with Karen. When she asked Marilyn for a drinking buddy, and then asking Tina to sleep with Stan, hehe. Karen was kind to Will, as she hugged him in the beginning. Very beautiful episode!
