It was a very unsettling look. One that actually made Stiles kind of nervous. He was very much not looking Derek in the eye when he spoke.

"Yeah she, um, told me about the the two of you being um...involved. Which I'm guessing you didn't want me or likely anyone else to know and I'm really, really sorry she shared," Stiles said. "If she was trying to reiterate the fact that she was a psycho to me then well done, Kate, 'cause that worked."

Stiles pushed his plate of pancake bites towards Derek, like that would make things better.
