Jess pauses in his exploration of the place when he hears something or someone move nearby. Both him and Jane stand completely still, waiting to pinpoint the source of the sound, to figure out or what it is.

Before that happens though, Jess pinpoints the source by, well, touch. He flinches away, almost overbalancing as he puts distance between himself and the person. At the same time, Jane lets out a caw that doesn't have any actual words in it, but still manages to sound like a swearword.

The immediate apology mitigates some of the fear they're about to be murdered, but hardly all of it. "Who's there?" he asks immediately, holding out his hands towards direction the person bumped into him from, not reaching out but creating a buffer between them.
