Wow, the writers absolutely hit it out of the park with this one. I've been looking forward to Mr. Johnson's chance to shine, and the wait was very much worth it. I'm not familiar with Patrick Kerr as an actor outside of this show, but he clearly brought his A-game for this episode. Truly a bittersweet backstory with an ending that serves as both an excellent conclusion to his character arc this episode and will likely be significant to the overall lore of the show moving forward. So far, this season has been much stronger than the first season, and I can't wait to see where things go from here - especially if we get more of Mr. Johnson! (Note: I'm also really glad that Giorgio is in a relationship with Nat and seems to have stopped hounding Cass. That was really hampering my enjoyment of the show, and I hope things between them (or lack thereof) stay as they are now.)
