I doubt we'll learn much (if anything) about The Incident, but I am stoked for more Hotakainen backstory anyway. Baby Tuuri in braids is so adorable!
I'm also interested in the side of present-day Tuuri we're seeing here. Tuuri can come across as the queen of denial because she doesn't like considering the possibility that bad things will happen or acknowledging negative emotions, but she's showing an impressive amount of self-knowledge here. She doesn't regret coming on the expedition not because she's convinced everything will be fine or because she considers the experience or scientific/cultural knowledge acquired worth her likely death, but because she can't envision a hypothetical scenario where she stayed quietly at home.
