This is the first episode of the series to feature both Caitlin and Archangel, though they aren't seen on-screen together until the next episode, 'Fallen Angel'. (edit) During the filming of this episode, Jan-Michael Vincent broke his right arm during a drunken argument with his (then) wife. As a result, for a great many shots in this episode, he is seen gesturing, opening doors, etc., with his left arm, while his right arm hangs limp. (Some shots are evidentially filmed before the break, as he is seen to move it a couple of times). (edit) The working title of this episode was 'Death Do Us Part'. (edit)

(Airwolf hovers in front of the casino window)
String: Darius, I'm taking you in for the murder of Lila Santini.
Solly: [to Darius] What the hell is he talking about?
String: It's over, Darius.
Darius: [to his hoods] I thought you said you took care of him!
String: Everyone else, clear out!
Darius: Get that thing! Get that thing! Get it! (edit) (String, disgusted at Dom's being jailed, and Archangel's lack of cooperation in helping to get him out)
String: You know something? I'm gonna take Airwolf down to that city hall, and I'm gonna put up a fireworks display that they'll never forget!
Archangel: Then you'll lose Airwolf, and you still won't have Dominic out! (edit)

Watch Jan-Michael Vincent's stunt double slip and nearly fall and hurt himself during the fight at night as he purses the intruder outside! (edit) After Vince takes a swing at Hawke and falls off the bar chair, watch Hawke's arm as he reaches down to pull him up – it's actually a "double"s arm, due to JMV having a broken arm, and isn't wearing the bracelet that Hawke is wearing! (edit) As mentioned under Notes, Jan-Michael Vincent broke his arm off-set during the filming of this episode. Watch when Hawke goes to leave Archangel's office – he opens the left-hand double-door, but he doesn't (appear to) touch the right-side one – it opens itself (presumably it was opened by some other means, to try and cover the fact that he couldn't use his right arm). (edit) When Dom's ex-wife Lila drops the locket that he has gone to collect, in the close-up of it falling to the ground, the chain lands in a different position to than in the next shot, as Dom bends over to pick it up.
(Also, in the close up, the carpet seems to be a different shade, but this is probably just due to the different lighting on the shot) (edit) As Airwolf takes off from the Lair, there is a shot of Dominic in his usual place in the rear of the chopper, yet just a couple of shots later, as the Lady is still rising from the Lair, he is seen seated next to Hawke (where he remains for the rest of the flight). The first shot seems to be taken from slightly later in the story, when they go on the secret mission for the Firm. (edit)

Episode Title: "Sins of the Past"
This is a reference to a TV drama movie starring Kim Cattral which aired in April 1984 (this episode occurring after). (edit)
