He'll go back to giving the little guy some ear scratches in a bit, for now Peter's watching the way this guy communicates and finding it super interesting.

"Brian, cool. Nice to meet you. Again, sorry about the grabbing thing, it won't happen again. I was just kinda freaking out about the..." He trails off, absently glancing where he thinks Brian's looking. He's a little off, looking over his shoulder rather than down on his shirt, but when he comes back around he finally notices his little hitchhiker. he moves to brush it off his shirt, but as soon as he does, he hears a blood curdling scream and stumbles backwards. He spends a second staring at the tiny spider that is now on the floor between them before looking up at Brian and pointing down at the spider.

"That, did you hear that!?" Oh buddy Peter sure hopes so.
