Dean was losing his mind. He knows it. It may seem like an exaggeration but he was actually losing his mind. He saw you jot something down when you were talking to someone on the phone. Sure, that itself isn’t weird or uncommon, but he saw you writing with your left hand! He’s known you for years, treated you like you were siblings, but never has he seen you write with your left hand.
He was sure that you were right-handed. Sure, you would do something like hold your phone or brush your teeth using your left hand when the other was occupied but other than that, you always used your right hand. Thoughts started racing in his mind, maybe you were taken and replaced by a ghoul or a shapeshifter? Maybe you got possessed by something left-handed. He was pacing in the kitchen when Sam enters unnoticed before he clears his throat loud enough for his older brother to hear.
“What’s up?” Sam says, grabbing a bottle of beer from the fridge and sitting down across from where Dean was standing. His brother was preoccupied with overthinking again before he calls out to him for the second time. After regaining composure, Dean sits on the chair across Sam, intertwining his fingers and resting his head on it.
“I think (Y/N)’s been possessed. Or switched out by some monster.” Dean’s accusation causes his brother to choke on his beer. Still coughing and gasping for breath, Sam managed to get a loud and confused “What?” out. “I think the-.” Sam cuts his brother off.
“Why do you think that? And how would something be possessing or replacing (Y/N)? They’ve been in the bunker for days, under our watch.” Dean shrugs at Sam’s questions before explaining.
“I saw them write with their left hand. And (Y/N)’s right-handed! I haven’t tested them with iron, silver, or holy water but they literally switched dominant hands!” Sam was flabbergasted by Dean’s explanation. He also knew that you were right-handed but surely there would be another explanation for you suddenly switching your dominant hand. Right?
The two talked in the kitchen for a couple of minutes before deciding to confront and test you with all they knew. And after it was settled, you walked into the kitchen, perfect timing. Oblivious to what conversation just took place in the room, you made a beeline to the fridge, taking out your tub of ice cream and setting it down on the table before sitting two chairs away from Sam. The two watched as you held the spoon with your left hand effortlessly, making their claims of you switching dominant hands becoming stronger with the evidence laid out in front of them.
When Sam seizes your left hand, making you drop your spoon that still had a scoop of ice cream, you reacted quickly by twisting his wrists to try and get away from his grasp. Your efforts were futile though when Dean also restrained you. The older man splashed you with holy water and cut your forearm with a silver knife. He ended the tests with a flashlight to the eyes, confirming that you weren’t a ghoul either.
“What the hell are you and what have you done to (Y/N)!” Dean yells at your face, annoying you. Using all the strength you could muster, you shove the stupid brothers off you. You examine the flesh wound they inflicted on you with a scoff before glaring at both of them.
“You idiotic brothers. Why are you guys like this? I try and prank you by hiding I’m ambidextrous the whole time we met and using my left-hand today and what do you numbnuts do? You shove me to the nearest wall, cut me with a knife, flash my eyes with a flashlight, and you make me waste a spoonful of my ice cream!” The two were silent, with guilt or something else, you wouldn’t know. And you can’t really care, all you can think of right now is your ice cream.
“You idiots are going to buy me another tub of ice cream. Oh, and ambidextrous means I can use both my left and right hand effortlessly. Just in case you didn’t know.” You stuff your mouth with ice cream, chewing on it while walking away from the kitchen, leaving the brothers dumbfounded.
