You know what? Peter doesn't need to chase after some crawling hellspawn. He barely flinches (alright, he gives a big flinch) at the hiss, then stands watching as the arsehole heads for the snack table.

Fine. He can be the lab rat. Peter will just keep an eye out for him as the night goes on, watch and see if he needs smiting gets worse...or better.

"Go fuck thineself!" Peter calls after him.
