Grey’s Anatomy Season 10, Episode 12 Spoilers: 8 Things We Learn From the Promo

April's wedding day is supposed to be a joyous occasion, but it seems like no one is in high spirits in this preview for Grey's Anatomy Season 10, Episode 12 — "Get Up, Stand Up" — airing next Thursday, December 12.

April's a bridezilla! April (Sarah Drew) storms into the hospital mid-primp, curlers in her hair and fire in her eyes. She finds Cristina (Sandra Oh) getting her bridesmaid dress altered. "You will look pretty at my wedding!" April yells.

A doctor freezes mid-operation: We track behind a surgeon as he or she walks into an OR and finds another doc staring at the patient at the table, standing stock-still.

Alex screams at Jimmy: We see a shot of Jo (Camilla Luddington) looking distressed and then one of Alex (Justin Chambers) looking furious, but with the way Alex is facing, we're guessing his anger is directed at the patient in the room, probably his father.

Cristina and Mer explode: Meredith (Ellen Pompeo) looks stricken as Cristina seethes, "Go to hell!" This is the end, folks. Brace for impact.

Owen and Derek mad with each other? Maybe Mer and Cristina aren't the only feuding parties in next week's episode. Derek (Patrick Dempsey) and Owen (Kevin McKidd) seem to be shooting daggers at each other as the elevator doors close between them.

Japril moment: Jackson (Jesse Williams) and April clearly share some sort of emotional convo on her wedding day. Please let this love triangle have some closure!

Arizona is an sopping mess: We see our fave one-legged doc (Jessica Capshaw) sobbing as she faces someone whose hair looks like April's. Hopefully those are happy tears!

Someone walks in on April: At the very end of the promo, April gasps as she sees someone in her bridal chamber before the wedding. Our guess? It's Matthew, and she doesn't want him to see her before she walks down the aisle.

Are April and Matthew on track for a happily-ever-after? Predict away in the comment section below.

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