When Biff’s lost in his own head, he stares off at nothing in particular, and his eyes will occasionally tighten as if he’s about to squint. Tara recognizes this expression on his face as he stands on his front lawn, in his underwear, under a very cold rain.

“Biff?” she says. “Biff! You’re going to freeze out here!”

“Hmm? Oh hey!” Biff focuses on her. “Nah, I’m okay. I… tried taking my clothes off to cool down, right? But it didn’t work.”

Tara looks up to see a belch of flame shatter his bedroom window.

“I was really hot,” Biff adds.
