Y/n l/n was a lab assistant in the avengers tower. Often times she would hang out with the science bros. And while usually she wasn't one to cause trouble. She did have her moments. Especially when goaded by Tony.

"I bet you 50.00 bucks she is too shy to do it." Tony boasted to Bruce.
"It's a bad idea anyways Tony." Bruce said rationally.
At that moment Y/n walked into the room, carting a tray of science equipment.
"Hey y/n! I bet you 50.00 Bucks you can't pull a fast one on Loki!" Tony smirked.
Y/n set down her tray of beakers. She stood there thoughtfully.
"Up it to 100.00 and I will try." She smiled.
"You are so on!" Tony exclaimed standing and shaking y/n's hand.
Bruce face palmed. He sure hoped this wouldn't end up in a prank war.

A few days later y/n had decided on a scheme and was ready to implement it. All she needed was to get access to Loki's room.
"Hey Clint?" She asked.
"Hmm?" Clint said his face full of sandwich.
"If I needed to gain access to Loki's rooms via the vents, what would be the best was to do that?"y/n smiled.
Clint washes down his sandwich with a swig of coffee.
"I can draw you a map!" Clint smiled. "Just be sure to capture whatever prank you do on tape please!"

Fifteen minutes later y/n was in the vents. Loki was out doing his daily sparring with his brother, so she had the rooms to herself. She dropped in effortlessly into his bed chamber. So far so good.

She made her way into the bathroom adjoining his bedroom and quickly found what she was looking for.

She grabbed the shampoo bottle twisting off the top and added her special vial of... something. She smiled to herself and climbed back into the vents. Now she just had to wait.

As it turns out she didn't have to wait very long.

"What in VALHALLA !" An angry voice was heard in the lab.
Tony shot an amused glance at y/n.
"Bruce hide me!" Y/n exclaimed. Bruce unceremoniously shoved her into the cabinet.
"Where is that little minx?!" Loki shouted as he marched into the Lab.
"What minx?" Tony questioned popping a blueberry into his mouth.
"The one who ruined my raven-black hair!" Loki seethed.
Bruce was starting to look a little green so y/n opened the cupboard.
"Here I am." Y/n said standing to face the angry trickster.
He looked at her and the anger slowly turned to mirth.
"Bravo Lady Y/N. It has been many moons since somebody had the nerve to stand up to me. You have earned my respect." Tony's mouth dropped open and he dropped his bag of blueberries. Bruce shook his head and went back to analyzing a substance.
"Perhaps when you are done babysitting these oafs, you would like to get some dinner?" Loki purred.
"I'd love to." Y/n smiled. Loki offered her his arm and they both headed toward the cafeteria.

Every relationship has its beginning and some are stranger than others.
