Grey's Anatomy Season Finale Preview: Caterina Scorsone Talks Amelia's Wedding Day Betrayal

The promos for Thursday’s Season 12 finale of Grey’s Anatomy (ABC, 8/7c) keep telling us that we are “cordially invited to the wedding event of the season.” And though we’ll be there with bells on, we can’t be quite so sure about the bride — those same promos suggest that Amelia’s feet may be getting too cold to walk down the aisle. Will the only “I do” she says be “I do not want to get married after all”? To find out, TVLine rang up Caterina Scorsone, the Private Practice veteran who plays Owen’s fiancée.

TVLINE | Let’s start at the beginning. What is going through Amelia’s head leading up to the big day?
Initially, she’s really excited. The fact is, she does love Owen deeply. And she’s never been in a relationship like this before. In the past, she’s gone out with kinda dangerous bad boys, or people who couldn’t quite understand her, so she knows that Owen’s actually a good person who is good for her — and she’s good for him, too. They bring out really wonderful, authentic things in each other [which also brings them] to a place of vulnerability that requires a lot of bravery.

TVLINE | That all sounds pretty good. Great, in fact. Where’s the catch?
The morning of the wedding, everything kind of explodes. A whole, unfortunate series of events takes place that sends Amelia into a tailspin.

TVLINE | Having to do with Owen or… ?
Having to do more with her family of origin and a perceived lack of support from her family and friends about the wedding. That spins her out. She was gung ho to go for it, but the morning of the wedding, she’s not getting the celebration and the party that she thought she’d get by becoming this adult who’s getting married. So she’s disappointed and feeling very betrayed.

TVLINE | I have to imagine that Meredith plays heavily into that. I mean, she was pretty nasty to Amelia last week.
It’s a very confusing situation. Amelia’s used to being perceived as the family screw-up. She was always trying to prove herself to Derek and her family, and prove that she was this awesome surgeon and a capable adult. Even moving in with Meredith, some of that had to do with proving that she could be a helpful adult. Meredith has kind of characterized her as this adolescent, selfish child in the past. So I think she was finally like, “Okay, I’m doing it all! I’m helping with the kids, and I’m doing my job well, and I’m part of this community!” And Meredith encouraged her to go after Owen and stop wasting her time, so I think Amelia very bravely decided to do that. She kind of believed that she stepped into a responsible adulthood that should be admirable. And that’s the exact moment when Meredith withdraws her approval. It confuses and devastates Amelia. There’s no way she can win approval from Meredith! I think that becomes a big piece of what’s going on with her.

TVLINE | It’s probably made even rougher by all the losses that Amelia has suffered over the years.
Right. She lost her dad, she doesn’t have a tight relationship with her mom, she lost Derek… All the really important people in her life, she’s lost tragically. She lost Ryan, she lost her best friend Michelle. She’s just had tragedy after tragedy with all of these people who were important to her identity. And a lot of that weight landed on Meredith. So Amelia really looks to her to give her permission to be who she is and be a legitimate member of society and the family, and she thought that she had done everything that she needed to do to get that approval.

TVLINE | Now, in the middle of this emotional crisis, with the clock ticking down to “Here Comes the Bride,” is Amelia even aware that her groom’s best man is in labor?
Thankfully, Amelia is blissfully oblivious to April’s situation. [Laughs] I think maybe that would have been the final death knell!

What do you think, Grey’s fans? Are Amelia and Owen really going to tie the knot? Do you hope they will? Hit the comments.
