Finally, Lydia rolled to face him. "You're right," she agreed. "We are doing this together, you and me. Not you, me, and Scott. Not you, me, and Malia. Not you, me, and Isaac, and not you, me, and the pack. Lydia Martin and Stiles Stilinski. That's it. If I wanted someone else's help, I would have asked someone else, but I didn't. I asked you," she said.
It was frustrating to get so worked up about nothing. So what if Scott offered to help Stiles, that didn't mean that Lydia had to accept the help. It didn't need to be a big deal, this was her body and she was the one who was going to be going through it, not Stiles. He was just along for the ride, at this point. But all the same, it wasn't fair to get angry at him when he was just trying to do exactly what she'd chosen him to do: support her.
Lydia deflated. "I'm sorry," she said, frowning. "Like I said...long day."
