Joe West. Best Dad Who's Not Your Dad Dad.
I seriously live for all scenes between Joe and Barry. And Joe and Eddie. And someday there will be an Iris and Joe scene where he will be like, "C'mon, Barry's the best, Iris, don't be stupid."
I don't know that I really care if Barry and Iris ever get together, but I love all the relationship dynamics on the show.
And when the show returns:
These two being bad guys together, but ACTUAL bad guys this time, LOL.
ETA: I forgot to say how much I'm enjoying Tom Cavanaugh as a villain? I mean, I think he's bad, but they're doing a good job of making it very vague and intriguing...anyway, having only ever watched him as "Ed" this is quite a creepy departure for him, and he's knocking it out of the park.
And, of course CAITLIN/RONNIE.
