The gryffindor quidditch team won yet again another game against Slytherin so, why would they need any other reason to celebrate?
As always, James and Sirius got some firewhiskey, butter beer, chocolate liqueur... whatever you could think of, they had it. The gryffindor common room was full of people dancing and talking, the music loud and the air heavy with sweat and who knows what else.
After a couple of drinks, you got overwhelmed by all the people and Marlene, as always, noticed immediately and took you to her dorm. Lily and Mary weren't there anyway, they were busy talking with people downstairs.
You could say that Marlene was your best friend for as long as you could remember and it showed. She sat you by the window before opening it and taking two cigarettes from her pocket and a lighter.
"You want some?" she asks, lightning her own cigarette while holding it between her lips.
