Is he - seriously - scratching her spider equivalent of a belly? She's too surprised and perplexed to really react outside of an involuntary twitch of her legs. When he deposits her on the shrub she crawls out hesitantly and sits there for a few moments.

Yeah sorry about your shrub there. She gets up and starts dusting herself off.

"Who the fuck pets a spider?!"
