Will was initially a bit scared (though he would never admit it) that he was strapped in and the Batmobile was all driving on its own and all. He could probably smash his way out but he didn't want to dare put a scratch on the Tumbler.

Everything was dark except the bright blinking lights and doohickeys within the 'mobile itself, until there was that last terrifying dark leap into the cave. Soon he felt the acceleration stop and slow, and he knew he must be in the Batcave. He grinned like the fanboy he was and fortunately the seatbelts/harness thingie undid itself and the door opened.

A sort of cool breeze slipped past his face and ruffled his hair, as he cautiously climbed out of the Tumbler and stepped into the Cave. Though it was mostly dark, he looked around. Perhaps it wouldn't hurt here to just take a peek...

His feet slowly left the ground as he levitated about ten feet in the air, seeing if he could see the entire cave from his vantage point. Of course he didn't realize he could smash his head against an unseen crag, and his eyes widened as he realized he upset a few Bats left in and they swirled around him as he yelled like a maniac and threw his hands up to protect his face.
