Someone says "He's been acting all pouty on the count of no-dos." with a completely straight face, and it works. The episode turns the emotional dial slowly, then all at once, like a kettle that has been patient for far too long. A character built on composure spends the climax losing it in the least composed way imaginable. The flashbacks are back, like an uncle who tells the same story at every dinner. Strong enough to make the next episode feel like homework you actually want to do.
