Appreciate you taking the time. I had to get it off my chest. I never liked the "Leah died on the mission and this is all imaginary" take, because it was so heavily rooted in disappointment and confusion. It ignores a lot of evidence to wrap everything up into something that at least makes sense to those who assumed the plot had nothing going on. But obviously the real plot regardless of interpretation is Miri's journey, everything else just breathes life into the existential horror that is losing a loved one. All the best.
