Isabelle doesn't know how Billy spent his birthday last year, but from the surprise on his face at this little party, it can't have been much at all. He deserves more than that, so Isabelle had been determined to do something, even if a party wasn't really what she wanted right now. Today isn't about her, it's about Billy, and she's determined that he have a good time.

He asks how they met, and Isabelle smiles despite herself. "He fell off a fire escape," she says, a smirk on her lips. Sometimes she can't believe that that's where they started all of this; with Billy falling off a fire escape and Isabelle pointing a knife at him.

"It was the day I first got here, and he was trying to show off. I threatened him with a knife, the rest is history I guess." It had been a long while before she entertained the idea of a relationship with him, though. He'd been dating someone else, back then, and mostly she'd liked flirting with him just to see him blush. Things are different now though, except she can't put her finger on when exactly the shift happened.
