I'm not sure how to quantify the emotions this audio made me feel, but the reveal at the end got me feeling some type of way and it really does explore one of the aspects I find so interesting about the Doctor and their companions: the way the companions are often the grounding force of the Doctor's morality, and how oftentimes they are given that enormous responsibility of keeping the Doctor in check without even realizing it.

I LOVE stories where the Doctor has to reckon with his own capacity for evil and this just hit every single button for me.
