Tread Perilously's Doctor Who month continues with a recent episode: "Lux."

When The Doctor and Belinda end up in Miami, 1952, they encounter racist policies and a seemingly haunted movie theater with a reclusive caretaker. Once inside, though, it becomes clear what is actually haunting the venue -- a living cartoon called Lux. Sure, he might resemble Mr. Ring-a-Ding, but he has his own aims. Will The Doctor suss out the truth or will he be stuck in an animated Doctor Who forever. And will he ever be able to get Belinda home?

For various reasons, Belinda is renamed "Belinder" and Justin is happy to see his favorite revolutionary playing the part. Erik forgets if this is the first or second proper Fifteenth Doctor adventure for Justin. The persistent rumors of on-set troubles during the making of recent Who are outlined. Ncuti Gatwa's dedication to the part on camera is a plus, though. Guest star Alan Cumming also gets his flowers, as does Linus Roache in a surprising role. Accents become an important part of the conversation with contributions from Charlie Cox. Erik continues to think of Paul McCrane as "prominent forehead guy." Justin disagrees with The Doctor's belief that he is Velma and a gaggle of fans agree "Blink" is still the best adventure.
