You and Billy were what he liked to call Partners in Crime. You kicked ass together. After the Boys pretty much kicked him from the Boys, he was on his own, but if he was going to just stop fighting Supes, well he would be damned. That's when he met you.

You and Billy were at your shared apartment, in the living room. The Supes were rogue, and it was your job to take down as many as possible, unorthodox ways and everything. That's what Billy liked most about you. You were a straight-up bad-ass.
