This is a very good episode it's once again another honorable mention in my book that doesn't quite make the list of personal fav but good all the same.
It's pretty much you simple Whodunnit story but here is different because the perpetrator is an alien. It's kinda predates John Carpenter's "The Thing" just like in that film the alien is a doppelganger which of course means it could change into just about anything and anyone but worst of all imitate behavior perfectly which makes zeroing in on the alien almost impossible.
I really like the dialog going on which is what really drives the story, as we see all of the episode take place in a dinner making this kinda a bottle episode. It's true we never know any of the characters and that's the point, they all total strangers that have all came from the same bus. The real detective are us as we are constantly exercising suspicion and trying to catch any hidden details that might give the alien away. I even like a little of this one customer whom has these really odd eyes and says a bunch of things that are a bit random; that guy was obviously a red hearing but it just goes to show just because someone isn't exactly part of the norm doesn't automatically make them an alien.
The main theme of this episode is on distrust on how little we truly know our fellow man. Despite the fact that all of them came from the same bus or are eating in the dinner together that doesn't make them all automatic friends or even talk to one another. Or even any one your close to, there is one moment with this young couple, the girlfriend then states she notices a couple of things about her boyfriend like certain mark on his skin and his behavior slightly changed. That moment also shows that distrust can happen closer than you think, we can sometimes find certain things out about your significant other that makes him or her a total stranger.
I really loved the twist at the end which is a real rug puller. Beware of the person that passes you by or even sit next to, you never know who they could be or where they come from.
