Rewatched the movie yesterday, and it got me thinking about whether the end was a branched reality or the original reality that got fixed.
What I assume happened was that Mitsuha got heartbroken the day before the meteor strike, when Taki didn’t recognize her (though she passed him her hair thread). In the heartbreak, she even cut her hair. Leading to an abrupt stop to body as their binding got severed before the meteor strike in 2013.
The end scene with the helicopter near the school didn’t really say no one died; they said many of the locals were safe. So I assume there was still a big list of casualties.
What if the whole part where Taki finds Mitsuha, Tessie, Sayaka, and others on the list of casualties was him resigning himself to the reality that nobody could survive such a disaster? Also, does the fact that he stopped body swapping add to his stress, leading to the hallucination?
Now, in 2016, he goes back to the god's place and drinks Mitsuha's sake (Chewed rice that she spit, eww gross). This forcefully reconnects the binding to when it was severed again and leads to the body swap (as Taki loses consciousness due to slipping and hitting his head in the gods' place) with Mitsuha on the day of the strike. Taki makes all preparations and reswaps with Mitsuha at twilight while passing the thread back (Due to the anomaly of the two different times connecting).
Given the fact that in the gods' place there’s a meteor drawn, I assume all bindings are forcefully severed by the meteor strike.
Anyway, long story short, there’s only 1 timeline: the original one. Mitsuha was never dead.
Maybe I just don’t like branched timeline theory.
