I always forget that they are both in this episode. It was on again last night. I went to bed in the midst of it and don't remember how it works out!! The two of them are the "bad guys." Anyway, I checked it on imdb to see if I could get more info on the plot, and found one reviewer who had a lot of nice things to say about Mitch. Here's the quote:
"Anyway, in this episode he has to struggle against an evil character, played one more time by the exquisite - and unfortunately so unknown - Mitch Ryan, whom he has already been against in other episode(s). I also find real pleasure to appreciate this actor's performances. I think of him in MONTE WALSH, that's where I discovered him. A great character for a great western. Ryan has an impressive physique, a perfect charismatic and tough, rough face. He should have been more enhanced in films or series. I would imagine him as a series lead character, so was Mike Connors in Mannix, for instance."
