The small creature in her vicinity catches her attention, but she dismisses it just as quickly, since she's used to bats flying around Gotham at night. She doesn't consider that she hasn't seen one in Exsilium yet, which is probably an oversight that Babs would scold her for, she's just so used to Gotham, especially when she's flying on a zip line.

The voice in her head, however, doesn't get dismissed, although she doesn't really register the words.

Mostly because as soon as the intrusion comes, she disconnects her line, flipping in mid air to land in a low crouch on a nearby rooftop, the grapple gun swapped for her bo staff. She extends it as soon as she's on solid ground, her whole body tense and ready to spring into action as she scans the night sky trying to pinpoint the voice's owner.

"Who's there?" She speaks out loud, but the words are clear in her mind as well; she has some experience with telepaths.
