Mini 30 Rock Reunion from Tracy's SNL

For those of you who didn't see, there was a small 30 Rock reunion during the monologue of Tracy's return to hosting SNL this week after his near fatal car accident. It was funny for the most part, and a real treat to see the main cast back together for diehard 30 Rock fans like me. Who do you all think changed/aged the most from the finale of the show to the "reunion" of this past week? I would say they pretty much all looked the same except Alec aka Jack looks a bit older...which isn't surprising considering he is by a good margain the oldest of the bunch.
