To the Batcave

Talia used Batgirl's tracker to see where the Batcave was, then reversed Batgirl all the way to it.

Once she was outside the Batcave, Talia input a command.

"Batgirl, tell Batwoman you've been compromised and that she needs to help you. I'll be waiting in the woods. You lead her to me and then, when she and I fight, back me up."

With that, Talia hid.
