Stiles sat in the living room, dressed to go, waiting for Dean and Cas while watching TV, ready to quickly storm them get affirmation without giving the whole story and making a run for it before Sam could get a word to him. As soon as Dean opened the door, Stiles was in his path. "Hey, Dean. Can I go to this party tonight? Everyone is going, and I need to act as Scott's wingman. Please?" Dean held up a hand to halt.
"Don't bother, Sammy called me. You aren't going anywhere but your room. You should know better than to try to snow me. Go." Stiles gave a pouting look.
"But-!"
"That wasn't a suggestion, it was an order! Go!" Damn it. Stiles turned a pleading look on Cas.
"Cas?" He put a deep whine on it. Cas gave a sympathetic look but didn't help at all.
"We are only trying to protect you from danger Stiles. Dean may seem harsh now, but please have faith that he is only thinking of what is best for you. Go to your room." Stiles huffed, stormed away up to his room and slammed his door before pacing. He quickly formulated a plan. He was 89% sure Cas would send Dean up in ten to fifteen minutes to check on him, or he'd come up himself. Either way he had a plan. He shut off the main lights and turned on a dim lamp before slipping into his bed. By the time he'd spent 10 minutes in silence, he could practically hear everything being said downstairs.
"Cas, I'm not going to check on him."
"Why not?"
"Why? Because I already know he's pissed, that's why."
"I'm not asking you to see if he's pissed, I'm asking you to see if he's okay."
"Cas, trust a human on this…"
"No, Dean. If I have to check on him myself, we will not be sleeping together tonight." Stiles snickered being practically able to hear Dean opening and closing his mouth like some fish. Stiles quickly mustered up a good fake crying sniffle and voice. Perfect… If he got this right those two might not bother him until morning. He got nervous as he heard Dean's footsteps stamping up the stairs, but stuck with the plan. Dean walked up the hall and opened Stiles' door.
"So, are you going to come down and have dinner, or just sit up here and sulk?" Stiles made a face of contempt regardless of whether or not Dean could see. He mustered up the fake sniffle and crying voice. "Just leave me alone! I hate you!" Dean sighed audibly.
"Fine. Your food will be in the fridge when you final stop acting like a brat." Dean probably didn't mean to but he slammed the door. Stiles could hear Cas and Sam arguing with Dean about being so hard on him, but Stiles knew he was home free. If they came up to check on him he'd see it as a betrayal, and they wouldn't betray him. He waited until Dean shouted at the persistent two. "Enough! If he wants to brood all night, I'm gonna let him, and I expect you two to do that same! Now, can we just go eat?!" Stiles got up and went to his window. He gently lowered himself down to the roof under it and jumped, trying to catch himself but tripping straight to his face. He ignored his misstep and scurried to his car, which he had parked far off on the curved driveway; He put it in neutral and pushed it until it was out of sight. Once he had he jumped in, started the jeep and drove off. He knew the party was at Lydia's so all he had to do is go and have fun while keeping an eye on Scott.
