I enjoyed this one. The whole concept of 'The Drunk Train' was hilarious, and some of the scenes on that train were rather funny.
Throughout the whole episode I was wondering who the actress playing Quinn was. She looked so familiar and I can't place it. Then around 7 hours later, it hits me that it is absolutely Amanda from Ugly Betty! I really enjoyed seeing her here!
The storyline was rather interesting with the Kevin/Robin proposal. It was really interesting, but the world almost fell to the ground with the last scene. Ted and TRobin AGAIN!!! That seems ridiculous. But I'll reserve my judgement of that until we see what happens in the next episode.
This was a good one. Hope the rest are good too! :)
