Reunited, and it feels so… lousy.

Alex's (Justin Chambers) dad is back in the episode of Grey's Anatomy airing this Thursday, December 3 — Season 10, Episode 11, "Man on the Moon" — and he's not looking so hot, as you can see in the sneak peek below.

As the scene starts, Jo (Camilla Luddington) brings bad news to her dark-and-twisty boyfriend.

"Alex, I have to tell you something you're not going to want to hear," she begins.

"Hm? Then don't tell me," Alex replies. (Seems rational to us.)

Jo explains that his dad Jimmy is in the hospital and going through withdrawal. Alex orders her to kick him out.

"I can't," Jo pleads.

"I can," he asserts, barging into Jimmy's hospital room. He barks at his estranged pops to get up and starts stripping him of his heart monitors.

Jimmy (James Remar), looking worse for the wear, greets him as "Son," much to Alex's disgust.

"I know who you are," Jimmy explains. "I didn't remember… I didn't remember till I saw you pissed off, till I saw you standing over me like when you were 15. You said you wished I was dead. I've been trying to get right since the bar. I still am."

"I'm not going to help a guy who made my life hell," Alex tells Jo.

"No, you're not," she agrees. "But I am because he needs help, and I'm a doctor."

Oh, snap! Most couples have their share of in-law troubles, but Jo seems to have hit a landmine with Alex's old man.

Do you think we'll ever see these three happily breaking bread over a Thanksgiving dinner? Or is Jimmy never gonna achieve Dear Old Dad status? Give us your thoughts below.

Grey's Anatomy airs Thursdays at 9 p.m. ET on ABC.
