S1·E26 The Gang

The Hayes gang is riding into Laramie, and one of the riders, Clay, is coming in to warn Dan. In a rare show of Dan's background, we learn Clay is his brother, that they both loved the same girl who went off with Clay and then died, and that Clay is not exactly a law-abiding citizen. But he still wants his brother and Johnny to win this fight against the gang, so he gets out of a sickbed to help when no one in the town will.
