Jealousy.. nasty bugger. Dean hates being Jealous it consumes him whole, but making you jealous.. that was worth it. After hearing you were going out with some douchebag guy you met at college while Dean was still hunting he was beyond pissed.. his Flora got a boyfriend before he could even work up the courage to ask her out.
So he did what any sane guy would do.. he got a girlfriend at your school just to make you jealous. He had his girlfriend ask you and your boyfriend on a double date and the whole time he was a complete ass.
Sure he didn’t actually cause a problem but you could see it in his eyes his sarcasm and dirty glares. Dean stood behind his girlfriend rubbing her shoulders his eyes locked on you, “so how’d you two meet?”
He watched as you leaned back against your boyfriend faking a smile.. it was so obvious you were trying to make him jealous to now and it was working.
