"Elevens a popular number." Considering Cassandra had said nearly the exact same thing about Talia when she had first arrived. She was making the connection, she didn't know if Faith would or not. "Perfect reason to hit something." and a perfect opportunity for her to observe a Slayer some more. Batgirl learned so much just by watching. Things just clicked for her.
She shrugged, a smile viewable behind her mask. "Batgirl. But I've had many spin offs from that name. I'll usually respond to most of them." Baby-Bats, Bat-chick, Freaky Ninja Bat Thing, and so on. There were apparently just so many possibilities.
"And you're Faith, the second Slayer I've met so far." which meant she had one more to meet, and Batgirl still wasn't sure who she was. There was supposed to be three.
She half wondered how long it would take a vampire to find them. Yesterday, she'd been around a Slayer for about ten seconds before nearly half a dozen had surrounded them. It it went past a minute, she'd be surprised.
