In Michael's fight against the electric monster, the narrator says his drones were bought and payed for by Tiffany. Shouldn't that be Alice?
I'd have to go back through because I can't quite remember the timeline of events but at one point Michael agrees with Tiffany to do something in exchange for a favor, I assumed the drones were the favor.
it is tiff because she owed him a Favour which he cashed in for the drones.
