Grey's Anatomy Season 9, Episode 7: "I Was Made for Lovin’ You" (airing tonight, November 29) promises to be a big episode, and we can't wait to find out what happens.

We can't make time speed up, but we can try to keep ourselves distracted by dissecting the sneak peek and previews of the episode for clues about what's coming up. So, of course, that's what we've done! Here are the nine most interesting things we've learned.

1. Arizona is back to work. In the sneak peek below, we learn that Arizona (Jessica Capshaw) is coming back to work at Seattle Grace-Mercy West. Callie (Sara Ramirez) seems nervous about it, but we're thrilled.

2. Owen knows about the lawsuit. In the same sneak peek, we find out that Owen (Kevin McKidd) has been informed about the lawsuit against the hospital. He seems to be handling it with dignity, but we're curious about how he feels underneath his calm demeanor.

3. Owen and Cristina are still on the rocks. Something Owen is not handling so well is Cristina (Sandra Oh) being back. Interestingly, in the sneak peek below she's the one who's reaching out, while he pushes her away, declaring that they don't work as a couple.

4. Is April pregnant?! In the sneak peek below, April (Sarah Drew) realizes her period is four days late and, as she tells Jackson (Jesse Williams) in a panicky voice, she's never late. Is she really pregnant?

5. Bailey and Ben argue about their wedding. In this sneak peek, we see Bailey (Chandra Wilson) telling Ben to call someplace and "get the deposit" back — apparently they're having a difference of opinion about the location of their wedding. But that doesn't stop them from being flirty!

6. A frisky patient. Meredith (Ellen Pompeo) will be dealing with a patient with an inappropriate tendency to grab women's chests. It looks like he's not just a perv, though — Mer seems to suspect his gubby ways are a sign of a bigger problem in the sneak peek below.

7. Derek's hand is still an issue. The preview for the episode (below) suggests Derek (Patrick Dempsey) will still be struggling with getting his hand fixed, and what it means for him if he can't.

8. Someone collapses. The preview also shows a doc collapsed in the OR, and Alex (Justin Chambers) shouting for people to get out. The doc looks like it could be Arizona to us. Does her first day back go wrong?

9. A "bombshell." The preview promises "a bombshell no one could ever expect" in the last five minutes.

Are you excited?
