"Let's pack up and make for the City of Silk again."

"Good plan.  ...I really want to figure out how the heck the stoichiometry on that cooking oil spell works out.  Just.  Randomly occurring thought."

"My gut says it's carbon dioxide and water probably?"

Packing packing...

"Want to go back the same way we got here- Flight, then Spirit World shortcut?"

"Yeah, obviously, oil is hydrocarbons, but what hydrocarbons?  How much hydrogen, how much carbon, there's oxygen in there also I'm pretty sure...  If you fiddle with the spell could you get plastic?  I don't know!  And yeah, that seems like a good enough travel plan.  ...Should I re-fox myself?"

"We can look it up at the library. Yeah, I think so, just for - weight's sake - do you know how? We get different methods, apparently."

"...No you can't, I don't think, they hardly have the chemistry to know exactly what they're making, do they?  And I know I don't know the atmospheric composition..."

"As for transforming - yeah, I have a few different options."  Transforming into a fox as she brushes up against Nicole proves that at least one of them is relatively convenient for this.

"That's a common one! I have it too."

Ear scritches time, and then-

Great winged fox!

Her coat and backpack rig again cleverly transitions into a saddlebag situation. "Foxwing Express would like you remind you that we are the only one servicing Windslab today, so keep your seatbelt fashioned for the entire duration of takeoff!"

And once she is as secure as she can be, off they will go back to town?
