"Nice receive" is obviously the highlight of this episode, and the season for me, but I wanted to talk about Atsumu and Osamu's conversation about hunger for food and volleyball.
Hunger for food and hunger for sports is a pretty obvious analogy, but I love how Osamu got into the psychology behind eating and passion for sports. Specially how addictive good food and success at sports can be, especially when you're lacking both.
It's a nice thematical callback to Bokuto's advice to Tsukishima on how beating a talented opponent and realizing your potential gets you hooked on volleyball.
