Do you guys think Nana dies

I saw a video on TikTok with the theory that Nana dies towards the end. I feel like as sad as it would be it’d make a really good twist to the story. That could be why we got loads of time skips to the future and they still didn’t have Nana and it could’ve been like a dog chasing its own tail and they were chasing a ghost. We feel the emptiness in the scenes without Nana and it could be hinting to how the Nan characters will spend the rest of their lives without her. I don’t know I think it’s a reach but what do you guys think. It’s a really interesting theory. I don’t think Nana does die but I think it’d be such a cool twist.
