A place for the Snowbarry drabbles and one-shots I've posted on tumblr. Ratings differ for each chapter. #7: Sugar Rush - In which Barry gets Caitlin to dance in the Cortex in the middle of the day, in her lab coat, in the wake of a botched experiment that she isn't supposed to be enjoying as much as she is.

AU – Being new to town Caitlin never expected to met the most annoying person in Central City who just so happens to be her new bosses son, Barry Allen with his stupid nickname, his ability to get on her last nerve with his smart mouth and irritating habits.

Author's Note: I wrote this fictional story the way I perceive The Flash TV Series. I think, since I am writing for #Snowbarry I'll exaggerate everything to make it the sweetest and epic.

Snowbarry R&R

Inspired by that teeny exchange amidst the madness of last week's episode. I know, I know… Iris/Barry is canon, but as we've seen with ARROW, this crew of showrunners isn't afraid to turn canon on its ear. So it's with that faint hope, I hold out for a Caitlin/Barry future. Or at least a nugget. Especially given the reactions of our duo as they gazed upon that byline.

Three months with Barry and it's like she suddenly understands why people make such a big deal about this kind of thing.
