Stiles was smart. Melissa knew that, and it was a good thing. He had a tendency to use his brain a little bit better than Scott did at times. He thought things through, but the other problem with that was that he was stubborn. When he made his mind up about something that was that. And he'd made his mind up about this without talking it through with anyone. His dad wasn't here, but Scott was and she was. And they were the only family that he had here, or at least as close as he had.
And even if he'd done research, and checked things out before going...it wasn't good enough for Melissa.
"You could have been the first sacrifice, kid. And the names could have been completely fake!" Melissa pointed out, and he could have, but that wasn't the main point that she needed to make. "You didn't take all the precautions you should have. You never should have gone alone. Let alone at all." His dad would have been upset, and she was channeling a good amount of that right now. She'd been worried, Scott had been worried, and even Allison and Lydia.
Reaching out Melissa put her hand over Stiles', taking a moment before she looked at him. His dad would have wanted to kill him, she was pretty sure, but obviously would have resisted. She was resisting the urge too, for making everyone worry so much. "I am glad you're back, but seriously...what the hell was so important that you needed to meet up with them?"
