Gwen jumps just a little bit out of her skin, it's true. She didn't expect anyone else to be up here at all, didn't expect to be interrupted. It never happens, at home; the only people who can really reach you are usually other spiders, and even that's only a fairly recent development. For a moment the silhouette of him, the muscle and extra limbs, makes her expect her spidey-sense to go off in that unique way it does when you meet another spider—there's plenty around the Society with extra limbs—but no, he's... something else.

The way this entire internal journey plays out externally is mostly very wide eyes, a jump backwards that she luckily catches before either falling or giving away her superhuman reflexes, and a look up and down Shouji's figure.

She's staring. She needs to stop staring.

"Oh, no, it's— it's fine, it's not like I own this spot or anything. I only just got here. To the boat, I mean. So."
