Shootout at Diablo Station - S2-E11
Plot hole: Well within earshot of the others in the small room, Curry comments to Heyes (purely for the viewers' benefit, since Heyes already knows it) that if Lom Trevors is killed, their amnesty will go with him. This information should have blown their cover, but for some strange (and unbelievable) reason, no one wonders what he's talking about. (00:19:00)
Shootout at Diablo Station - S2-E11
Plot hole: Curry slips out of his bonds and hides in the secret cubby hole beside the fireplace, right under the four dozing outlaws' noses. But when he's found, the wooden door over the hiding place has to be pried off - very noisily. No one else was free to nail that door shut, and there's no way he could have done it from inside - at least, not without waking up the outlaws. (00:30:30 - 00:34:50)
