Told You They'd Freak by GeckoLand
17 parts Complete
A series of short stories about Barry Allen and Sebastian Smythe being twins. Some stories in here are part of one huge story of their lives, which probably is canon by now all over Wattpad. Some are just random. I really can't tell them apart myself, but they're fun.... so enjoy! (Note: I accept requests.) I don't own CW or Fox, although I wish I did, but then I'd have taken both shows underwater to drown with me.
