Showershorts:
Elliot was, despite her sometimes crazy, obsessive compulsive side, a very patient person. At least, she always had been with JD. When it came to planning a wedding, she still had that book with magazine cut outs and phone numbers to call for reservations (that were already made ahead of time, either way), she had locations picked out, and different sets of decorations for each place, as well as a different dress to match with the rest.
Maybe JD had something that calmed that side of her down a little. Maybe it was the same thing that made her believe every single thing JD told her, as obvious of a lie as it might have been.
However, there were some things she would just not accept. Her sanity had limits, believe it or not.
"Please, Elliot! Pleaaaaase!"
"No way, JD. I'm already letting you and Turk walk down the alley together doing the moonwalk, even if that might mess up the carpet or remind my grandmother of that freak accident with the moonwalk guy who stole her kidney." She blew at her bangs in that way JD loved, but it wouldn't distract him from his Master Plan.
"...I thought that Grandmother was dead."
"So did I!" She laughed then, shrugging. "But apparently there was a mess up in her home and it was another old lady that died, or something."
JD paused for a few seconds before shaking the information off. He had to do that a lot with Elliot, but he loved it.
"Come on, please! How bad can it be?"
"JD! I said no! Everyone's going to look at you and not at me and no one will see how well my hair was done or how my dress falls perfectly behind me!"
"I...I'LL LET YOU WRITE MY VOWS!"
"...Really?"
"Yes."
"Deal. You wear your shower shorts to the wedding, and I write your vows. Spit on it." They spat in their palms and shook hands, JD grinning like an idiot and Elliot smiling proudly. They both rubbed their hands against their pants with a grimace as JD ran off to tell Turk the good news, and Elliot headed to tell Carla of her success in writing both their vows to match.
