"IF YOU THINK PERCY'S BEST MAN WOULD BE ANYONE OTHER THAN GROVER I WILL SHOVE THE LIGHTNING THIEF SO FAR UP YOUR A** YOU'LL BE SPEAKING IN CHAPTER TITLES FOR A MONTH" -tatertotskie on tumblr. (and inspiration for this one shot)
"Bro what do I do?"
"Hey Percy calm down. You've only been engaged for a week. I don't remember you being this nervous about proposing." Jason was standing in front of Percy's bed in Cabin 3. Where the son of Poseidon was having a nervous breakdown about his wedding in two months.
"That's because I knew she would say yes." Percy face planted into his pillow. "But now I have to actually plan a wedding."
"Well Annabeth is going to do most of it isn't she? I mean, they call it the bride's day right?"
"Yeah, but she wants me to plan what me and my groomsmen will wear." Percy groaned, lying on his back. "I have to pick something. But I have to make sure she doesn't hate it. But I need to make sure I like it or she'll know I'm picking it because I think it's what she wants. And it has to not clash completely with what her bridesmaids are wearing."
"I think you're overthinking this just a little." Jason couldn't help but chuckle.
"But I'm responsible for what all my groomsmen wear." Percy looked up pleadingly. "Do you think Piper would help?"
"Definitely." Jason assured him. If Percy used the baby seal eyes, Piper would say yes in a heartbeat. "But have you picked them yet?"
"Who?" Percy lifted his head.
"Your groomsmen?"
Percy bolted upright. "Crap."
"I'll take that as a no."
"But how many do I pick? Literally everyone in this camp could be one. Where do I start?"
"How about your best man? Who's the first person that comes to mind?"
Percy didn't even have to think before jumping up and grabbing Jason by the shoulders. Staring into his eye and smiling wide. "Isn't it obvious?"
Jason felt touched. "Percy . . ."
"I gotta go find Grover!" Percy sprinted out of the cabin. He quickly ran back to the door to shout, "thanks Jason!"
"No problem." Jason's awkward reply went unheard as Percy was already gone.
