Hello. :)

This is a figure-it-out-as-you-go one-shot, so I'll see you at the end for my regular A/N.

Enjoy! :)

"Hi." was all that she could manage, really. After the last few hours, she was surprised she managed a single word at all.

"Hello." He greeted back.

She smiled. She missed that voice...or perhaps she didn't. She'd been so mad at him for so long, but every moment since that phone call she'd been thinking longingly of his voice, his touch, his lips and, most importantly...him. She did miss him after all, even if she was repressing it for a reason that wasn't even a reason anymore.

"You're...Meredith." He said slowly, a little uncertainty in his voice, watching as she sat down in the chair beside his bed.

"That's right...Theo. I'm Meredith." She confirmed, feeling her eyesight blur. He knew her name. He. Knew. Her. Name.

"I'm sorry." He apologised after a long second of silence.

She faltered, "For what?"

"For making you cry." He answered tentatively.

"Oh-" She breathed, just as the tears rolled. She pressed the sleeve of her jumper under both eyes to absorb her tears. "No. It's okay. These are happy tears."

"I wish I knew too."

Another stab in the heart. All she'd thought about was herself, but this must have been hell for him as well. "Yeah?"

"I think...I think I missed you. I think-" He paused, gathering his thoughts, clearly battling to talk. "I didn't remember you but...I think I...my- I mean-"

"Your heart missed me?" She suggested. "Even if your brain couldn't remember me?"

His eyes sparkled with tears too. "I feel less...empty now. I think it's because my...my heart is happy now."

Happy-tears truly did gather in her eyes this time. "My heart is most definitely happy as well."

He smiled back. He liked it when she smiled, and he was glad to hear that he was cheering her up a little. He couldn't imagine what the last seven months must have been like for her.

She felt terrible for asking, because she knew it would ruin his smile, but she couldn't help but ask, "Do you remember the accident?"

"I..." He paused as the lump in his throat cut him off. "I think...a little bit. But they're not nice memories."

She nodded. From what she'd heard, and considering the severity of his brain injury, she could have guessed that.

"I think I remember some memories of the hospital I was in. More later when I was more...aware; I think I was pretty out of it for a while. And then I think I remember everything from rehab, and the fall...but...everything else is-" He paused. "Not good, not...not much."

"That's okay. How are you feeling, by the way, after the fall? If you're in pain or tired and want me to come back later-" She offered, despite the fact that she felt as if someone would have to drag her out of the room kicking and screaming for her to agree to that. She was just trying to be nice; he clearly must have hit his head pretty hard for some of his memories to come back.

"No. I...I'm okay. I...got lots of headaches before, when it first happened so...this isn't bad." He replied. "This is...maybe the best headache."

She smiled. "I hate to agree because it makes me sound like a sadist but...I'm really glad you fell this morning."

"I think it's strange too but...me as well." He agreed. "I would've never known you. Never remembered you."

"And I would have never got you back-" She squeezed his hand hard, holding it up to her face. She wanted to kiss his hand, but she thought that wasn't the best idea.

"Meredith. Can you tell me my name again. I promise I'm not making a memory joke-" He snorted. "I really don't remember."

She giggled. She couldn't help it. He'd always loved jokes. Corny, terrible, you-laugh-because-the-joke-sucks-not-because-it's-actually-funny jokes. "Your name is Derek."

He took a second to nod. "I think...that sounds like me. More...now than before."

She smiled. "I'm glad. Because I do like the name they gave you but it's a little weird not to call you Derek."

"I like Theo. They named me well, I think."

"Yeah. But...I'm just glad to have my Derek back. I...I mean-" She paused. "Obviously, things are different now. It's going to take some time for you to figure how to...how to be you again. You were Derek, and then you were Theo, and now you're a bit of both so...I'll support you whatever happens."

"Because...you're my wife."

"Yeah. That's right."

"But I don't really know you."

"And I'm going to be as patient as possible while you learn about me."

He stared at her for a second before nodding. "Meredith."

"Mmm?"

He swallowed before tentatively asking, "Who am I?"

"Well...you are whoever you turn out to be but- Derek...the old Derek who I knew that you may or may not be in the future-" She sighed. "He liked coffee ice cream. His favourite drink was single malt scotch. He was a fan of fly fishing. He was a cheater on the cross word puzzle. He refused to dance in public. His favourite book was Sun Also Rises, and his favourite band was The Clash. And then, I don't know how much you remember- but you have a mom, four sisters, and what-feels-like a hundred nieces and nephews."

"I think...I remember people but I don't know who they are. But...I think they're my family."

She nodded. "They'll come back. You'll remember them. You'll remember everything."

He nodded, but didn't speak.

She didn't either for a few seconds; the face he made when there was something on his mind hadn't changed. "Ask what you're thinking of."

"What?"

"You're making a face, that means you're thinking of something. Tell me what is- or ask me your question." She elaborated.

"Since the day I woke up in hospital, I've been having this...repetitive dream- I think it's a dream, at least. And you are in it. Neither of us say your name but...it's you."

She nodded. "And what am I doing in the dream?"

He smiled. "Well...Luke - my occupational therapist - thinks I'm mad because it makes no sense but-"

"That's okay. Maybe I can help you out." She reassured him, desperately hoping to hear about this dream. She wanted to know what was left of herself in his memory.

"We...we're in this room with these wooden cupboard things. Except the cupboards have no doors- they're like cubby holes, I guess. And then...you're sat on this bench thing. And then-" His smile grew. "I'm holding this like...blue piece of paper. But it's small. Like a-"

"Post-it note." She breathed.

He swallowed as she stole the words right from his lips. "You know what I'm talking about?" He asked, surprised.

"That was our wedding, Derek."

"Our wedding?" He repeated.

"We were ready to go and get married. But then both of us had to stay at work. I was sad, so you said we could have a wedding right then and there in the attending's lounge, which is the room you were describing, by the way. I thought you were mad but went along with it. And then we agreed we needed to write our vows down, but all I had was a packet of post-it notes. So...post-it note wedding it was."

He smiled. "It was real?"

"Yeah. It was definitely real. The dream wasn't a dream, it was a memory...of us, Derek. The whole time."

"Why are you looking at me like that?"

He smiled, and kissed her. "We're married."

She smiled back as he pulled away, and returned to his side of the car. "We are."

"I have to call you my wife...and you have to call me your husband."

"Hey, I thought I was supposed to be the one who was freaked out by commitment, not you." She retorted, although there was a broad grin on her face.

"I'm not freaking out." His smile expanded. "I'm just...it's just-"

"We're married. Like...you're my husband and I'm your wife." She finished for him. "I get it. Jesus Christ, trust me, I get it."

"So you are freaked out by commitment still?"

"No...not freaking out-"

"So we're just...we're both in shock, aren't we?" He supposed. "I mean, we both know that that's what happens after you get engaged but...still-"

"Maybe it's because it was on a post-it."

"Mmm." He murmured. "Maybe."

"I loved it, by the way. I feel like it wouldn't have be us if we weren't in some way total weirdos."

He smiled. "Growing up a nerd and a geek, I'm happy to accept that title. And I'm so extremely glad to have you as a wife."

"Can we kiss again?" She asked, anamoured by what he had said.

"Oh, Mer. You underestimate me." He winked. "I have much more than kissing in mind for tonight."

"But...we did actually get married...right?" He asked slowly, almost suspiciously.

"Yeah, of course we did."

"Like...in a church?"

"No. Just with a lawyer dude in a courthouse. We didn't even do like proper vows, just the legal stuff."

"Oh." He breathed. How odd. How very, very odd.

"You loved me so much you didn't care. And-" She smiled as she squeezed his hand. "No pressure- but I'm really hoping you're going to love me again one day, enough to understand what was going through our minds."

Meredith was in a rush, as always. Derek still struggled with housework and helping out so while they weren't a one-parent household, they definitely weren't a two-parent household. But, despite that fact, she paused for a solid few seconds.

It was nothing special, really. He was just a dad sat on the floor with his kids. But it was special to her. Eleven months ago he had disappeared into thin air. Ten months ago she officially decided she despised him. Nine months ago she started searching for him in the hopes of getting divorced. Seven months ago she gave up her search. Four months ago, she recieved a phone call, telling her a man who had been in a car accident and lost his memories had just suffered a fall in physiotherapy and woken up asking for one Meredith Grey, who he claimed to be his wife. Two and a half months ago, she took him home, along with Carolyn who came to help out. Six weeks ago, she left him and the kids alone for the first time. A month ago, he could recite ninety percent of their story, half from his own memories that had slowly come back to him, and half from the stories she had told him. Two weeks ago, she returned to work with no concerns about him. And today, he was doing nothing special, really. He was just a dad sat on the floor with his kids. But it was special to her.

"Meredith."

"Huh?"

"Are we gonna talk now?" He asked.

"Oh. Yeah." She agreed, still partially in her own world.

Both kids left him, clearly listening, leaving the pair alone.

"So...what did you want to talk about?" She asked as she sat on the floor opposite him. He'd made massive progress in his physiotherapy, and didn't really require her to do things like that anymore, but he still winced when he got up off the floor and she always hated to watch it.

"We got married on a post-it note."

She smiled. "We did."

"And- what you said that day at the hospital about me eventually loving you enough to understand...I think I'm at that point. I think...I know- I love you."

Her smile grew to a beam.

"And...I think I want the world to know that again. I think...I think I want to tell the world."

"In a church."

"No, no. Just-" He sighed. "As much as I love the post-it thing now-"

"You want a post-it free vowel-renewal." She finished for him.

He smiled. "If that's okay with you."

She smiled back. "After the year we've had, I think I'd get married in a church with a big poofy, white dress without a single complaint."

A/N: Hello, hello! :)

Hopefully, you have gathered that this was an amnesia fic, a very popular trope that someone requested. Also, Lucy, I kind of incorporated your request for something post-post-it wedding with the flashback. Two pigeons, one rock...in the infamous words of Carina DeLuca.

Hope you enjoyed! :)
