The futility in his voice was evidence and it shook Lydia down to her core. This really was what he was convinced was best, and with a horrible sinking feeling, she realized that nothing she said would be able to convince him. No matter how strong either of them could try to be, this was something they couldn't win right now. There was no victory in this debate, only sadness and cold that radiated down deeper than anything she'd ever known.
She couldn't feel her own emotions anymore. It was like she had gone completely numb without a moment's notice, and she tried valiantly to pull herself together, despite the fact that she felt her blood run as cold as ice. It was worse pain than she had felt when her parents got divorced, when Peter Hale manipulated her into doing his bidding, because this was being done for her safety. Not one person ever considered her safety. Lydia had fallen into the category of being a target most of her life or an aspiration for someone to attain. This felt worse than being used or neglected. She couldn't place what exactly the emotion was, but she knew it was not good.
"You can't be alone again, Stiles. I can't be alone. Whatever it is, we're a team. All of us. You can't go isolating yourself like this." A surge of anger rose up in her and Lydia dropped her hand from him, too disgusted with herself for running away and thus giving him time to think this over. "That isn't helping either of us."
