Okay gang! Two more characters means two more voice actors!

June Hadley: Amber Gray. Easy. In her roles as Helene in "Natasha, Pierre and the Great Comet of 1812" and Persephone in "Hadestown" she has a voice like I've never heard, it's cheeky yet down to earth, old yet eccentric and a bit flirtatious. It makes double the amount of sense because she plays Persephone to Patrick Page's (remember, one of Silas' voices) Hades, and their relationship mirrors their's quite a bit.

Leslie Fallon: Roberta Colindrez, she's performed in musicals and podcasts I really love, she plays Joan in "Fun Home", and features in "Alice Isn't Dead" and "It Makes A Sound". I really wanted Leslie's voice to be unprecedented, this very low, kind of relaxed voice coming from such a tiny, skittish looking creature. She can sound very impartial and completely relaxed, like Leslie is in the face of everything.
