Dean's little red riding hood

When the Winchester brothers break into their fathers hotel room; hoping to see him after he disappeared on a case, only to find a girl in place, how will they react?

Scarlett's whole family was massacred by a werewolf, she would be dead too if John hadn't saved her. He took her in because she reminded him so much of his youngest son, Sam.

What happens when the brothers take Scarlett with them to find their father, will sparks fly between her and a certain Winchester? Or will death and despair get in the way?

(I'm going to try and follow the basic plot the season one, but I'm going to change the dialogue and everything else up a bit. Hope you enjoy!)
