Ep. 3: Stand By Me

Ep. 6: ...And Lose My Calm

In the second part of chapter 6, Harry descends into multiple black rages, Yudkowsky finally demonstrates a good example of the planning fallacy, and a plot twist is introduced. Anthea is dispirited, Jake and Elisa are unimpressed, and a dog makes a cameo. This episode spoils a plot reveal from later in HPMoR. Content warnings: this chapter mentions child abuse.

Ep. 5: How I Learned to Start Worrying ...

In the first part of chapter 6, Harry enlightens McGonagall about the planning fallacy via an incredibly maladaptive coping mechanism.  Elisa, Jake, and Anthea are forced to question the limits of authorial intent and why there are so many alleys in Diagon Alley.  Content warnings: we touch on Alzheimer's; medically assisted suicide, cryonics, and other end of life considerations; suicide; and mortality/death from about 0:50:00 to 1:05:45.
