"William, will you help me with something?"
"........ I know that look."
"Pleaseeeee???? I need to know."
"Y/n no. Find someone else."
"William!!! Please??? You don't want me to leave, so help me out!!"
"....."
William stared at the floor, his face blank, but he was evidently thinking hard about the matter. You smiled, grabbing his arm and squeezing lightly, to show him how serious you were about this. He sighed, shaking his head in response, pausing a few more seconds afterwards.
".... alright. ..... fine." He replies with a huff. Immediately you grin, doing a celebratory squirm.
"Yay!!!! Thank you thank you thank you!!!!"
"... mmhm. You're wrong, by the way. Jim is. Incapable of caring. In that way. But, if you really need to see for yourself, fine." William says, raising an eyebrow over at you. You just smile, determined to test your theory nonetheless.
"Alright come on- he's watching through the cameras so should be able to see us as soon as we get out from under this fort. You ready???" You ask, grinning uncontrollably. William just sighs and nods, adjusting his position.
"Yeh. Ready as I'll ever be." He replies, before you both crawl out from under the fort. Standing up, you hug William tightly and he (more or less awkwardly) hugs you back. You smile, pressing your face into his chest, prolonging the hug for just about a minute. When you pull away, you look up at him, and very very slowly lean closer to his face. As predicted, the door slams open, and there's a very, very angry Jim. Eyes flaming with hatred, he marches in and grabs William by the tie.
"You. Have. Work. To. Do." He growls, William blinks a few times, evidently completely surprised that his boss was being so discernable. Jim then proceeds to drag William out of the room. Just before they're out, William glances back at you, looking surprised as hell, with an 'oh god Jim is jealous' expression. You stand there, partially in shock, partially smug from the fact that you were right.
Jim was jealous.
