What. She’s basically got photographic memory. The whole series is built on flashbacks to her memories.

She’s dense as fuck when it comes to interacting with people, sure (though she’s been getting better), possibly due to being an elf, possibly due to having spent most of her life alone in the woods, and she’s extremely disorganised, but she remembers perfectly every single word of conversations held a thousand years ago.

Remember the sour grapes, remember her conversation with Old Man Voll when she was offended at the suggestion of her possibly not remembering until she realised he really was senile, remember how she could tell that the steaks in the restaurant tasted different than they had over eighty years before.
