I've been stuck a day behind everyone else, not seeming to be able to watch two episodes in a sitting to get caught up, but I just wanted to say I hate these scenes with Finn and Jackie. I'm assuming it's going in the direction everyone has seen coming from the start, that he's Chase's father rather than his half brother. I liked those two as brothers. It was one of the best things about Finn. This plays as though someone just realized there's a 25-year age gap between the actors -- when it isn't how they read opposite each other or how they've been playing their scenes from the start (IMO) -- and went with the biggest "shocking soap twist" imaginable.
And, really, did anyone need or want another layer of complication for Finn? His back story was already overwritten, with all that stuff about the dead wife with the incurable disease, besides the entanglements he's actually played onscreen over four and a half years. Hayden is still out there somewhere, on pause.
I hope they hit abort on this somewhere along the way, but even if they do, the revelation that Jackie did a story on Finn when he was a first-year resident, and they had sex right before she married his father, is overly convoluted and alienating. Finn's been on the show for four years, Chase for two, Jackie was briefly an important character in the early '80s, and Finn's father has barely walked through. So I don't think any character involved is central or well established enough to get this kind of realignment -- the way, for example, Alexis was when we were asked to roll with her being the mother of Sam.
