In the preview for Grey's Anatomy Season 9, Episode 4: "I Saw Her Standing There" (airing October 25), it looks like Jackson (Jesse Williams) and April (Sarah Drew) have slept together again. Scratch that — they’ve slept together a lot.

We see that they can’t keep their hands off each other, even at work. And they’re not the only ones having a workplace relationship. Cristina (Sandra Oh) has a “sex friend” that she tells Meredith (Ellen Pompeo) she doesn’t even like.

As for Owen (Kevin McKidd), he’s wallowing with Derek (Patrick Dempsey), telling him he doesn’t think she’s ever coming back. Somehow we doubt that. And Arizona (Jessica Capshaw) finally tries to walk with a prosthetic leg, but it’s not going to be an easy process.
