She sits next to Darren in English.
Bella also waves. "We had Mrs. Adams as a sub in English today. Darren says you know her," she remarks when he's near enough.
"... Lynn Adams?" says Vernon. "Huh. I know her, yeah. Can't say I'm surprised she just so happened to show up in your English class today. She does that, creepy as all get out. You want a demon expert you talk to her, she knows more than I do."
