No, rest assured that was not his best episode, but it was one of them.
I adore this show, but Dr. Helm occasionally does disappear, which is a tad irritating. (In one ep, Tessa, the main character, pretends to faint--and the villain Montoya yells, "Get Dr. Helm!" Tessa gets up in a flash, while I'm screaming "FAINT, you stupid woman, FAINT!") Unfortunately he's not in next week's either. sob I miss my Peter!
Good ones to watch out for: "Death to the Queen", "The Serpent", and my favorite, "Vengeance".
And I agree, Cass--the man definitely has wonderful chiseled features! I hope you like the show.
