Stiles wasn't going to stray far from Scott's side. He was entirely human, as far as anyone knew, and he had his best friend's back. Not just Scott, but there was Malia and Parrish to consider as well as Peter and Kira and...yeah. Stiles insisted on being with Scott for this conversation because he could provide a different perspective. He was the liability, the weakest link, the one the others protected with their strengths and abilities.
"We just want to clear the air about a couple things," Stiles offered. He wasn't sure letting Scott talk was the best idea. But Scott was the one with something to lose, so Stiles was going to try to let Scott take the lead. Even if Scott was sometimes horrible at this kind of thing. Maybe this time he'd do it right.
