Mike and Erica in “Unfinished Business”

Mike

This isn't about saving Derek. It's about saving Holly. Vecna took her. And yeah, now he's after Dipshit Derek. But we have a plan. A plan to both save Dipshit Derek and find Holly. But the plan is... It's a bit insane. But after it's over, I don't think Tina's gonna wanna talk to you ever again.

Erica

Well, why the hell didn't you just start with that?
