This episode was great! It was an all around well-written 40-something minutes that hit many notes, but mainly summed up by its title, delving into various past conflicts deeper with an overall theme of bygones be bygones and leaving things in the past, be it Walker and Twyla's history, Chief James's marriage and frustrations with Walker, Auggie and his teen problems with Faye, and Stella and Colton, Bonham and Dan. It has a really fun vibe with Cass and her obsession with some 90's fake show and references throughout. They better do a fantasy episode about that. There was more continuity and character development, building on Twyla and Walker's earlier undercover times. There was a nice Archibald Faketwist near the end, but overall it really brought this ancillary character that was once collateral damage and a means to an end to the forefront and possibly as a love interest for Walker given his current sitch with Geri. And Twyla and Walker's chemistry is great. I hope they bring her in on more episodes. The ending was a great beginning. A fun episode that I hope will not be the last of its kind...
