"Da Vinci's Demons" Episode 3 "The Prisoner" Starz TV series, review, no spoilers

A great episode this week.
Our hero often looks like he is battling ADHD, but then so does Johnny Lee Miller in "Elementary".
Leo, in much of the series, is either drugged or drunk - dealing with his 'demons'. And we had quite a few demons in this episode - either real or imagined.
Da Vinci finds an ally in the usually incompetent Giulino Medici (Tom Bateman). Who knew? Loved the possessed nuns (very Ken Russell's "The Devils", 1971). The atmospheric abbey was quite Hammer Horror. More please. We had Leo solving the mystery of the wacky nuns while our favourite villain, Riario (Blake Ritson) talks strategies with the mysterious prisoner. Their board game of black and white pieces looks like the ancient Asian game of Go.
This game is played throughout the episode, parallelling the machinations occurring in Florence. A clever touch, Mr Goyer. As well as the motif of the caged parrot, who can escape but does not.
More furious bird sketching in the marketplace (such a great scene in Episode 1). The brief shot of sunrise over Florence was glorious.
Clarice Orsini (the very busy Lara Pulver - the lovely Irene Adler in "Sherlock", also in "Spooks" and "True Blood" - all great shows) proves herself to be no fool. Beware, Lucrezia.
Liked the blindman's quality control in the arms factory, Leo's spontaneous painting-licking and the frenzied bonking among the Medici horses (a stable relationship between Lorenzo and his filly???).
Leo's feverish nightmares were particularly graphic this week - reanimated corpses, scalpels and ripping apart chest cavities.
I assume we will see more of Riario's Abyssinian slave (if the naughty pope doesn't monopolise her time).
