So I just rewatched Arrival (2026), and by now I have pretty much everything about the plot figured out. How Louise’s mind started working after communicating with the heptapods, why Renner’s character left her years later, why the heptapods contacted Louise specifically (they knew she was gonna lose her daughter to an unknown disease that was probably gonna hit the heptapods three thousand years later – and they knew that, by then, the humans would have enough technology and would have enough knowledge of the heptapods‘ language to help them understand the cure), etc etc
But one thing I cannot figure out why in the scene in the “future” with the general – 18 months after the arrival of the aliens on Earth –, Amy Adam’s character didn’t remember what she said to the general to stop the war
The movie clearly points to the general’s wife dying before the heptapods’ arrival, and said general also knew there was no way Louise could know about his wife’s last words – so that’s when he understood her mind worked differently and he needed to trust her. Louise spoke those words to him because she figured out that, in the future, her character would hear those words
So why didn’t she, in the future, remember the words that she spoke 18 months earlier? The general knew he needed to give her his personal number and his wife’s words. But why didn’t she remember what she said?
The movie proves that Louise starts understanding time differently than others, but her memory of her past couldn’t change – she tells the heptapods ”who is this girl?” because she hadn’t had Hannah yet. But her position in the research and contact with the heptapods was due to her previous paper and knowledge of languages, so she knew her past. And her mind only changed after meeting the heptapods
So why did future her looked so confused when talking to the general when she had already called him on his personal number and spoken those words? Why didn’t she remember what she said?
We knew ”present“ her got the vision of the future and that’s why she got to know the number and the words, but ”future” her would already know then because the call had already happened
So why did she look so confused when talking to the general? Why didn’t she remember what she had said herself to stop a war? It‘s an information too important to forget only 18 months later – and she didn’t even remember she had already made the call. She didn’t know any of that had happened
