The Winchester brothers had heard the distress called about some sort of evil witch around the Small town not to far from where they were, so they both took action on investigating what the small problem was which turned out to be a huge one,

it seemed that the witch they'd be facing would be a lot more, from what they could pick up, the witch casted a lot more spells and and does far more than what any normal one could do,

Sam curiosity took the better of him and when he notices a strange light coming from one of the buildings, he could hear someone do a chant, it was you, the witch

"What in the hell..?" He said confused, but he may have said it out loud, which caused you to stop the spell and make a run for it, and him chasing after you,

You ran for good amount time before Sam cough catch up to you a stop you, cornered you panicked a swung a punch right across his face which made him tumble back a bit a feel his face,

"Ouch!" He exclaimed a bit angry and slightly impressed about how much force you put into that punch.
