Your bedroom window opens suddenly. Mysterion then jumps down and onto your windowsill

Mysterion: “New Kid. Get dressed and meet me out front. Hurry. The night awaits. Cool room.”

and then, he jumps back down and onto the grass below.

You climb out of bed and get into your Super-suit. You quietly leave the house.

Mysterion: “It’s about time. You know how hard it is to look mysterious when you’re just standing around in some kid’s front yard? It’s pretty fucking hard.” etc
