Stiles stopped talking when Erica placed her hand over his mouth. Yeah, he needed that or he would have gone on and on and on. He tried to answer Erica's question, but it came out muffled since her hand was still over his mouth. he reached up and moved it and repeated what he had said. "She's Derek's little sister." If she wanted more information, she could ask. But Stiles was just going to keep things simple for now.
"Try?" he said as he watched her look him over. "I seem more...?" he asked, eyebrow raised, waiting to see what word she could come up with. And there it was. "Seasoned? You make me sound like a piece of meat reading for the grill," he joked. He did get what she was talking about, though. "It's been a few years since the last time I saw you. Maybe that's why I seem different to you now."
