I asked for pre-canon prompts what feels like a million years ago and this was Liz's idea so I gave it a go, and then let it sit in my drafts for two months half-finished so here's what I've got so far! There's also SO much dialogue in this and I am sorry for it because I'm so horrible at writing it.

Harvey was engrossed in reading up on the notes he needed for court the next day when he hears her gasp. Interest piqued, he raises his head from the papers, opening his mouth to speak through his intercom when she appears in his doorway, a rectangle of white card in her hand. Walking towards his desk, she stands opposite, practically hopping on the spot.

"Yes, Donna?" he muses, a smile ghosting across his face.

"I was opening your mail," she breathes, shifting her weight from one foot to the other.

"And?"

"And, this", she slides what she was holding across his desk, "came for you. A wedding invitation, for next weekend." She was almost squealing.

He rolled his eyes, studying the piece of card, "Since when do I get invited to clients' weddings?"

"Since always. I just usually send them an apology and the most expensive item of their registry."

That earns her half a scoff and an eye-roll from him, "And this one is different because?"

Harvey swears he had never seen anyone looked so rooted in shock to the spot before.

"Are you being serious right now? Ben Wright is marrying Alannah Fisher", she gasps, huffing at his blank expression.

"She's the most in person right now in theatre", she tried again, "She was in the play I saw last month that I didn't shut up about for three days after?"

No reaction.

"Harvey! She just won a Tony!"

He stares at her blankly, "A who?"

"Are you kidding me?"

He tilts his head, looking amused. "It doesn't matter to me what it is, Donna, it's going to be a no."

"You have to go!" she hisses. "It's going to be the wedding of the season. There's going to be so many high profile people there! Red carpet probably, paparazzi and everything... "

He scoffs and raises his hand to throw the invite in the trash when her hand catches his wrist and he stills.

"I want to go as your plus-one."

"That would be a problem Donna, considering I'm not going."

Her eyes dart from left to right frantically, "Harvey! I'll work on Saturdays for the next three months and won't even complain once."

He laughs, looking thoroughly unconvinced, "No you won't."

The hold on his wrist tightens and she leans closer, her hair slightly falling into her face. "I didn't want to have to do this-"

He raises an eyebrow, carefully trying not to focus less on her grip on him and more on calming down his steadily rising heart rate.

"If you don't go to this wedding, and bring me as your guest – I might have to let it slip to Louis about our little trip last August."

"You promised you wouldn't-"

"Maybe I'll forget I promised. How do you think Louis will feel…", she drops her voice to almost a whisper, leaning closer to him so her breath brushes across his cheek, "…knowing, that we went mudding without him, and you even enjoye-"

"Do not finish that sentence, Donna.", he croaks, his voice coming out a lot less put together than it usually does, "Begging and a threat all in one argument, don't they cancel each other out?"

"Want to take a chance and find out?"

He holds her stare for a beat and sighs, throwing his free hand up in mock surrender.

"Okay, fine." Said through gritted teeth.

In a flash, the grip on his wrist is gone and he almost lurches forward at the loss of contact.

"Excellent!", she sings, "That was the choice I thought you'd make!", turning to return to her desk,

"Now, if you'll excuse me, Harvey. I've got some online shopping to do."

Exhaling, he leans back in his chair, starting to wonder what on Earth he had just been suckered in to. An entire day, at a wedding – arguably one of the most romantic settings that he could think of, with Donna as his date. This was teetering on very new territory for them, things had been slightly strained after the entire Stephen debacle and his declaration that the two of them together had bothered him, whatever that meant to him deep down. Donna was his best friend, he couldn't remember anyone else, aside from Marcus and his Dad - who was such an intrinsic part of him and his life. Even the thought of addressing what really bothered him about Donna and Stephen's relationship was something that he was pretty sure he'd rather throw himself in front of a bus than speak to her about it. But it was becoming clearer to him that one day, they would have to discuss it, and it wasn't going to be a comfortable topic.

The days counting down to the wedding flew by in a whirl of Donna parading into his office at various times of the day to show him what she was considering getting his client as a gift from him as if he had any idea what the man would actually like other than stunning legal representation. Day by day her excited chatter seemed to die slightly, and he started to sense something he had never felt from Donna before: nerves. She was nervous. To anyone else watching her talk animatedly about all the other guests that would be there, some she had even guest-lectured for classes she had taken in college, or that she had worked with before in plays she'd done, you would think there was so much excitement in her there wasn't room for any other emotion, but he could read her. He could tell, from the way her eye twitched as she gushed about how fantastic the day would be, and how she blinked slightly more than usual and spoke in a slightly higher pitch than normal about how she hoped the rain would stay off for the whole day so as not the ruin the outdoor reception. Small things that nobody else would notice. Small things that would only be noticed by someone who had spent over a decade watching her every day for every tell she had, even though he would never let on how much he could actually sense each and every feeling she had. It was cute, he thought, well – not cute. Endearing maybe. That she cared so much about this day to be nervous, and he thought even though she had had to resort to blackmail to get him to agree to go, he was almost looking forward to it. Spending time with Donna outside the office was something that didn't happen so much anymore, not in the last few years.

Over time it had gone from something second nature in them to sometimes meet up on their days off, to meet for a coffee post her Saturday morning yoga class, drinks in his penthouse on Friday nights after work when they still had files to go through for a case that really could have waited until Monday morning. But that all had changed to office hours only now, perhaps extending to giving her a ride home every now and again, but that was it. Something had changed in them, and it was getting harder and harder for him to ignore that it wasn't something that he felt right with. He missed her. Which was a crazy thought, to miss someone when you still see them every day, when they sit twelve feet from you and on the other side of a glass wall, but he did. And he was almost sure, from the fleeting moments that pass them – a brush of his fingers on hers as he hands her a glass of scotch, their eyes meeting in mirth as she listens to whatever newest rant Louis has for him at eight in the morning – that she didn't always look away first, that her hand wasn't the first one sometimes to pull away when they happened to sit too close on his sofa in his office and their little fingers would touch.

So, he was looking forward to the wedding, almost, the thoughts of spending all day also mingling with his client's nearest and dearest still making him half-wish he had called Donna's bluff on her threat.

As always, feedback is always welcome. Wedding chapter will be up when I have finished it! :)
