"Clearly, being in love makes you an idiot"

- Samantha Chase

His car had been sent for repairs. Why he used that heap of junk still, she didn't know. But she had offered to drive him to work. True to her word, JJ showed up at Reid's apartment. She was a little early, but she knew he would be ready, punctual as he always was.

Just when JJ raised her hand to ring his doorbell, she heard noises coming from within. One was definitely her best friend's.
"Stop it! No! Nooo!"
Full Agent mode on, JJ took her gun out of the holster and listened again. Reid was shouting. He was in danger.
Screaming "FBI!" at the top of her lungs, JJ kicked the door open. Two faces, white with shock, looked her way. One was her co-worker's and the other of a dark-haired woman.
'What in the...'
JJ lowered her gun on making out the position they were in. The woman was straddling Spencer, whose shirt had come un-tucked. She had him pinned down to the floor.
'Tickle fight. Seriously?'
Spencer got up in such a hurry the woman fell off him. He explained,
"JJ, this is Dr. Monica Knight. She's uh... she's..."
Monica took up the reigns. She adjusted her own clothes and walked to Jennifer.
"Hi. Dr. Reid has told me so much about you. But he didn't prepare me for just how beautiful you are", Monica extended a hand, "I'm Monica"
A little flattered and a little taken aback, JJ shook her hand.
"Pleasure. I'm Jennifer, as you know. And sorry about the door, Spence. I thought you were being... attacked"
Spencer had tucked his shirt back into his pants. He cleared his throat.
"Um, I forgot to tell Monica that you were driving me to work. She, uh, she came over to offer to drive me to... anyway"
The two women watched him fumble with and gather his bag and holster. Monica had her arms folded while JJ stepped out into the hallway. Dr. Reid only had to turn to Monica for her to say,
"I'll stay over and get the door fixed. Don't worry"
She looked at JJ as she said,
"I have the day off today. So..."
"Thanks", Spencer said.
He glanced at JJ, who promptly looked away. She tried not to smile when her peripheral vision caught Monica kissing Spencer's cheek.
"Bye", he mumbled.
"Bye", Monica smiled, "It was nice meeting you, Jennifer"
"You too", JJ smiled back.

The moment they were out of his building, JJ was grinning so wide her cheeks hurt.
"Please, promise me you won't tell the others. Especially Garcia. JJ? JJ!"
She clutched her stomach and began laughing.
