Alice and Julia have decided to go through with the plan to transfer magic from Julia to Alice - and Alice is almost painfully excited. They’re going to use a repurposed hedge witch spell that originally was used to steal magic.
They start - and are interrupted by Penny who attracts their attention by possessing a singing fish.
This is not the most dignified way to communicate.
He warns them that he’s seen this before - and it killed the witches in question. But it’s also Fogg’s spell - yes Dean Henry Fogg.
He’s not doing so well - and he’s not exactly happy they’ve been keeping Julia’s magic from him but, as they point out, he’s been very drunk all the time. He doesn’t deny this or make excuses - because he’s a magicless magician, a Dean without a school, and an unemployed blind black man in an even more prejudiced America (it turns out they were using magic to “increase tolerance 38% which Henry is already scathing about and clearly unimpressed by how little tolerance that actually amounted to). In other words, Henry has plenty of reasons to be drunk.
He does tell them about the spell - and that they need the flesh of a magical creature. Specifically an incubus. Which means they go to an incubus to ask to use his penis
And I was all ready to roll my eyes because this is freaking Magicians but at least someone on the writer team decided that they’d used up their quota of forced sexual situations for the next 11 centuries and backed off. Turns out that the Incubus isn’t into sex, feeds on stress, and is happy to lend them his regrowing tail.
