What she wants to do is this.
She finds Tony - ahahaha, she can teleport now, no spending a pentagon every time wincing when she remembers where they come from - and says:
"Let's go blow my weight in quarters on arcade games and finish that James Bond marathon?"
(She has other friends, who she knows better than Tony, but they don't know about stuff, she wants to keep it that way, and she's going to be in a bit of a mood about stuff for a while; better to put them off until she's got her equilibrium back.)
"Awesomesauce. Do any of those have skeeball? Who'm I kidding, every arcade that exists has skeeball - okay, which ones have DDR?"
Soph hops into the red car's passenger seat. "So apparently I can torch now, you don't have to be extra extra careful driving me."
And they're off!
"I mean you should be careful, you just don't have to, like, not speed or anything radical like that."
"Bella says I can decide whether to tell Mom and Dad that I'm only recently real. That's how she said it, 'only recently real'."
"I kinda don't think I will. Not soon anyway. My friends neither. I like having pockets of normalcy."
"Yeah, but, like, if you get pulled over or something right now what are you even going to do? Being dead seems like a hassle too."
Soph wants to play DDR first. She is really good at it. "After this you can beat me at something with cars in it," she says.
