"It's nice of you to grace us with your presence," I say, leaning on the open passenger-side window of Amelia's car. I am joking, of course. I'm actually really glad she's spending so much time with Arizona. She's good for her. They're good for each other. But, it's still fun to tease her.

"Do you want a lift or not?" She retorts.

"I was hoping some of Robbins' perkiness would have rubbed off on you," I say as I get into the car. "Apparently not."

"How's it going with you guys?" Maggie asks, clambering into the back seat.

"Good. Really good, actually!" Amelia smiles as she starts to drive towards the hospital. "She's so fun and exciting." There's a look in her eyes that I haven't seen before. "I knew she was smart, but she thinks so deeply, too. She's kind and thoughtful..." I've never heard her talk about anybody like this before. She may have felt these things, but she certainly never verbalises them to other people. This girl is in deep. If it was with anybody other than Dr Sweetheart, I'd be worried. Maggie and I smirk at each other. "And, she's funny. Like, really funny!" Amelia chuckles as she remembers something. "The other night, she..." Her rambling stops as she notices the exchange between us. "What?"

"Look at you," I continue to grin.

"What?" She asks again, starting to get frustrated.

"You love her," I tease.

"Meredith, we've been dating three months..." No denial. She definitely loves her.

"Oh, my God, you so love her!" Maggie joins in. Amelia rolls her eyes as she realises this teasing is going to be relentless.

"Okay, we're not talking about this anymore..."

Confidently, I stroll into the research lab, tumour sample and notes in hand, but it's already occupied by the last person I want to see.

"Oh... Sorry, I thought this was free today," I apologise to Callie.

"No, stay. I'm just finishing up," she insists, never moving her head from the microscope.

Awkwardly, I take a seat and start flicking through my notes. I'm not really taking any of the information in, I'm just trying to keep my eyes busy. Callie continues to look through the microscope, checking some bone fragments. Somehow, I can tell she's about to start digging into my relationship.

"So..." Here it comes. "You're having sex with my wife?" Wow. I wasn't expecting it to be quite so blunt.

"Ex-wife," I correct her, trying to appear unfazed, keeping my eyes on the page.

"Uh huh," she says, dismissing my comment. She spins around on her stool to face me. "Where do you see this going exactly?"

"Callie," I warn, looking up from my notes. "I'm going to tell you this once," I say, firmly. "This is absolutely none of your business." She simply scoffs at me, ignoring what I've just said.

"You're at the end of a long list, Shepherd," she says, cockily walking over to the table I'm sat at. "She's slept with half the women in this hospital, you know."

I see red and stand up quickly, coming face to face with her. This could be misconstrued as an act of insecurity; like I'm unsure of Arizona's intentions. But, I'm not. I know she wouldn't use me like that. What I'm actually mad at is that she's trying to suggest that Arizona's a slut. Though I'm a good six inches shorter than Callie, I don't feel intimidated. I just feel angry.

"You're wondering why you lost her?" I ask, with raised eyebrows. "Because you can so readily talk shit about her like that," I spit the words out, and her smug look changes. "Arizona is wonderful," I say, adamantly. "And, you'd have realised that when you were together if you could take your head out of your own ass for more than five minutes." Okay, now I'm shouting. Time to dial it back a little. "Relationships are a two-way street, Torres. Next time, try showing your partner a little respect." Maybe that was a step too far. She looks almost hurt. That's enough now, Amelia.

"You really think I need relationship advice from you, Shepherd? Are you kidding?" She says, starting to wave her hands around. "You dived headfirst into a completely flawed marriage and want to give me advice?" she says, spitefully. "You need to focus on your own relationships and your own happiness before poking your nose into mine!" She storms past me, slamming the door behind her.

And, I stand there in stark realisation: She's right. But, not in the way that she thinks. I am happy and I am in love. I know this to be true. But, the last time another human made me this happy, I had a brain tumour.

Fuck.

I'm re-arranging OR schedules when Amy's anxious voice brings me out of my thoughts.

"Come with me," she says, urgently, as she approaches me. "Now," she says, marching past me, and down the corridor towards the elevator. I follow her, wondering what's got her spooked. "Where's Maggie?" She asks.

"She's in surgery," I reply, quickly. I scan the room to make sure no one else is within earshot before asking my question. "What's going on?" I ask, worried. The elevator bell rings and we get in. Amelia presses the closed door button, several times in quick succession.

"I need you to scan my head," she says, once the doors are closed. "I think it's back." Surely, she's not saying what I think she's saying. "I think the tumour's back."
