Childhood friends. That's what you and Jason were before Bruce Wayne adopted him: inseparable. You used to run around helping him with his thefts, and he used to help you and your mom with the cakes she used to sell. After he went away, you didn't communicate. Ever. He forgot about you, for sure -- but you never did. He was always there, in the back of your mind, only good memories popping up along with his name. His smile, his pretty dark hair, pretty eyes, and those moments where he just made you feel so cared for.
You were finishing your second year of college, and everything was going as well as you expected to. You had a good job (rare thing in Gotham), lived in an apartment your dear late godmother had left for you, and managed everything else.
Walking out of your last class on a familiar rainy Thursday, you bumped into someone... tall and very hard, almost like a wall. Already mumbling a thousand apologies, you felt a gentle and heavy hand on your shoulder, and then you finally looked up to his eyes.
