Grey's Anatomy Finale Recap: Jo Makes a Shocking Confession

The Grey's Anatomy Season 12 finale was ostensibly about Amelia and Owen's wedding, but it was Alex and Jo who stole the spotlight in the final minutes, thanks to Jo's shocking confession that the reason she can't marry Alex is that ... she's already married.

Amelia and Owen each wondered if they were just settling for the other as they prepared to get married; Meredith and Alex lamented that they'll never find anyone as good as Derek and Izzie, respectively; and April and Jackson grappled with the fact that they might lose yet another baby.

Back at the loft, Jo drunkenly explains to DeLuca that her husband was abusive, so she left and changed her name so that he could never find her.

In addition to any physical damage to DeLuca (those punches were wince-worthy, even as a viewer), it's uncertain at best whether Alex and Jo's relationship can survive the fact that he doesn't even know her real name.

[...] after some initial hesitation in which she came thisclose to being a Runaway Bride, Amelia's feeling pretty positive about her and Owen's future as she starts making her way down the aisle, thanks to a pep talk from Meredith (Ellen Pompeo) over Slurpees.

[...] while she's there, she starts having contractions that get worse and worse until her water breaks.

Ben gives her a pelvic exam - awkward! - and discovers the baby is breached, which means he's going to have to perform an emergency C-section right there on Meredith's kitchen table.

Arizona can't handle Sofia seeing her other mommy so unhappy, so she shows up at Callie's (Sara Ramirez) doorstep with Sofia and a pair of plane tickets to New York.

Later, with April out of commission, Riggs brings the rings to Owen and they make tentative amends, with Owen proffering a halfhearted invitation to the wedding reception.
