By the time she got down the fire escape- even after sliding the last ten feet or so- Batman was already down. She really should look into getting some gadgets.
"Jack-O-Lantern? That's what the Scarecrow left with his murder victims and had printed on the milk cartons..." She paused for a minute-- things were looking less and less good for poor, innocent, kidnapped Dr. Crane. "Kind of on the nose, don't you think?" She asked rhetorically.
If there was any place in Gotham that her bike was safe, it was probably outside the GCPD HQ. She did hate to leave her baby behind, but seriously? Anyone who even called themselves an amateur mechanic would leap at the chance to ride in the Batmobile.
She looked apprehensively at her bike then shrugged and started towards the Batmobile, pocketing her keys. She even thought about asking if she could drive, but decided not to push her luck-- at least not until after they'd taken care of this business at Arkham.
