Wanting to get his brother back for the online dating prank, Aaron enlisted the help of Jess and Morgan.

"And whose gonna be cleaning up the bathroom Aaron?"

"You know the rule Jess, whoever makes the mess cleans it up bathroom wise. Plus I'm due to go on a case tomorrow. For once I am so glad I'm going away."

"Man you do like to torture your brother don't you Hotch?"

"He deserves it Morgan, so you in?"

"Hell yeah."

Whilst he and Morgan, sarin wrapped the bathroom toilet, Aaron having told Jack that until the prank was over he and Jess would have to use the private bathroom in Aaron's room, which Jack was quite happy with. He too was in on the prank. Jess used her job as a nurse to get hold of some laxatives.

Sean arrived home late that evening, having worked a late shift at work. Aaron greeted him with a cup of coffee, which Sean was grateful for. Aaron told him Morgan was crashing and hanging out for the evening which is why he was there.

An hour later, they were watching TV in the living room, Jack having gone to bed, when Sean began to have serious stomach pains. He jumped up, holding his bum and ran for the bathroom. About a minute later they heard yelling.

"AARON! Who the hell sarin wrapped the toilet?" They heard Sean shout in pain and then heard the sounds of him hurriedly and frantically sorting out the toilet before they heard his yells of pain and relief. He didn't come out for the next half hour and even then he spent the next couple of hours running back and forth to the bathroom, promising to clean it the next day when he had the day off and felt better. But Aaron had succeeded and was happy. The next day, for once, he was happy to leave on a case that took him out of town. By the time he got back, Sean was plotting serious revenge against his brother!

Aaron was so tired the night he got back from the case, he fell into a deep sleep. Wanting revenge and to get his brother back with the same hand in water prank Aaron had played on him a few weeks earlier, Sean crept into his brother's room. Luckily Jack was sleeping over at Henry's house.

The next morning, Sean heard his brother yelling.

"SEAN! I'M GONNA KILL YOU!"

"IT WORK THEN DID IT BRO?" Sean smiled and was happy, especially when an irate Aaron came out of his room freshly showered and carrying an armful of wet sheets and his wet pyjamas!

Now it was Sean three, Aaron two….Aaron so wanted revenge but first he wanted revenge on the other guy who'd put him on online dating websites…

The next day, he'd managed to get J.J help him pull the prank against Will. She came in the next morning smiling and nodding.

"It work then did it?"

"Yeah, though he did wonder why I slept in the spare bedroom but it worked Hotch. He was not a happy man this morning…says he's so gonna get revenge…after he's cleaned the bed and done the laundry…"

"What's this about a bed guys?" Dave happened to walk into Aaron's office at that very moment.

"Hey Sean did it to me J.J the other night but I'd done it to him a few weeks ago."

"Sean played that warm water trick on you Hotch? Made you wet your bed?"

"Yeah. Dave. But I got J.J to play the trick on Will."

"J.J, you made Will wet the bed?"

"Yeah and I slept in the spare room….."

"I thought you were the one who wanted revenge against Sean Aaron for that online dating prank?"

"I got my revenge, thanks to help from Morgan, Jess and Jack. You know the day we left for the last case? Sean spent the whole of his day off cleaning the bathroom. I'd spiked the coffee he drank with laxatives Jess got for me to use on him AND me and Morgan sarin wrapped the toilet. Everyone but Sean spent the next couple of days using my private bathroom."

"Aaron Hotchner! You are a naughty boy!"

"Yeah but Sean got me back but I am so getting revenge on him….."
