Oh, Amelia. What are we going to do with you?

On Thursday's episode of Grey's Anatomy, Amelia (Caterina Scorsone) is just peachy after her pregnancy test came back negative. Seriously, she's totally fine. Nothing to see here, and nothing to even talk about — really, Owen (Kevin McKidd), because everything is great. Completely. Fine.

Until it's not. After her teenage patient experiences a sudden brain bleed and dies, moments after Amelia reassures him he's going to be fine, Amelia has a full-on breakdown. She runs into an on-call room to compose herself, where Alex (Justin Chambers) happens to be chilling. The floodgates open and Amelia tells Alex all about the baby she had with Ryan, and says she's scared to tell Owen the full story because she's afraid he'll hate her for it.

Is Grey's Anatomy teeing up a romance between [spoiler]?

Despite Alex's assurances to the contrary, Amelia continues to push Owen away while putting on a brave face. She breezily mentions that they should probably hold off on trying for a baby so that they can enjoy their time as newlyweds, and tells him not to wait up for her since she'll be working late.

TVGuide.com chatted with Scorsone about whether this has the potential to drive a serious wedge between Amelia and Owen. See what she had to say below. (For her thoughts on Amelia's reaction to the pregnancy test, go here.)

TVGuide.com: Amelia tells Owen that she wants them to hold off on having kids so that they can enjoy their time as newlyweds. But will she ever be ready to have a baby?
Caterina Scorsone:
I don't think she knows what the end of this is gonna look like. Right now she's spinning so hard that she is just trying to buy some time. I think she really had a plan about how her life was gonna look, against all odds. She is with this amazing guy, they're married, and they have a house, and everything is looking like it's actually working out for her, which she wouldn't have believed in a million years would happen a couple years ago. Here we are, and now, against her will, her emotions are coming up to kind of sabotage her and everything in her life right now. So she's just desperately trying to get back in control. She's creating a bit of a smokescreen of her life, positive spin, so that she can just have time to get it all packed back into the little boxes that she had packed for herself. And we don't know if she'll be successful at that or not. We haven't gotten there. But I think that's what she's doing. I don't think she knows where she's headed right now.

What's holding her back? Does she blame herself for the loss of her previous baby? Does she think she'll be a bad mother? Or is she trying to protect herself from potentially experiencing another loss?
Scorsone:
I think in Amelia now, it's all such a whirlwind. She's so triggered and so terrified and I think it almost goes beyond her comprehension, what's happening right now. Because I think she's quite split. In her conscious plans, she wants to be a mother. She loves Owen. They would be great parents. They're responsible surgeons and married and they have this house, and she's great at taking care of kids and so is he, and it all makes sense. Except, she's been so traumatized by loss generally, of all these people in her life, including her dad and her father and her best friend and the father of the baby, and the baby. She's so traumatized by loss, and particularly by loss of the people she loves the most, that yeah, I think the idea of having another child that she could potentially lose - or of not being able to have a child for whatever reason, it's just too much for her. She's completely overwhelmed by the thought and by the possibilities. She's almost in an emotional catatonia right now.

Is this something that will drive a wedge between her and Owen?
Scorsone:
I don't know. I know that the stakes are really high for both of them. I don't know what Shonda [Rhimes'] plan is, but yeah, these are huge core issues for both of them. So we'll see if they'll be able to navigate this storm or not.
