It's not like he's totally unfamiliar with being an outcast, but also, he totally agrees with this spider. He might even have said something to that effect, if it weren't for the fact that she's suddenly petting him.

If he weren't so exhausted he totally could have dodged, okay...anyway his ears twitch a bit at her touch, and he opens his mouth to complain--only to close it again. If he was gonna complain he probably should have said something the first time she did this, and besides, he only just got comfy here, he's not gonna get himself kicked out over her (admittedly very soothing) scritches.

After that short confused pause he finally reaches for the snacks, keeping an admirably straight face despite the sudden lack of eye contact. "....You....have certainly made yourself comfortable out here." If he leans into the pets at all please don't say anything.
