Wolfgang startles and there's a moment there where him toppling over into the ravine is a very real danger - but he gets his balance and straightens, turning, the concern on his face easing into pleased recognition. "Oh, hello, Data," he says, completely unconcerned about the several hundred foot drop to a messy death an inch and a stiff breeze away from him. It's funny that heights don't make him nervous, considering he's scared of everything else in the world - cats, loud noises, physical contact, the Militia, the number two. He's even scared of bees a little.

Considering the idea he's had where gravity is a force he can control has, up to now, remained theoretical - he's too chicken shit to jump off a rooftop and pray - he could stand to demonstrate more caution around heights.

"No, I guess it is not." He takes a step back, but negates it by leaning forward, bent at about a ninety degree angle, and peering down the cliffside. He can't see anything down there that could be causing a will-o'-the-wisp, which means that while he won't rule out a natural cause, it's likely paranormal in origin. If he were still twelve, that would have been his immediate reaction.

After a moment, he straightens and half-turns to face Data, pointing out in the general direction of the light. "Have you seen any more of those around here?"
