A group of men get together a nickel and dime poker game on a train. One man refuses to play, and the bulk of the story tells the reason why in flashback. Flashbacks are quite useful in 26 minute episodes, but they also let us know that the protagonist will be OK (although we've seen in the series where that isn't the case).
Actor Robert Horton pretty much has to carry the episode (BTW, I like that he has a mustache in the present that he didn't have in the past; This shows a little effort). The poker part is pretty tense and its not obvious where it is going. We get two surprises near the end.
Season 2 has been weak so far, but this episode may turn it around.
