"Once the event ends, your characters’ memories will be somewhat fractured and mixed up. Recalling the events of the weekend will feel like recalling an especially vivid dream, but they are honest to goodness memories. If you need a number for reference, figure that a character can remember about 80% of what happens during this three-day period."
Yeah with Emet's own memory I figured he'd likely maintain a huge majority of it because that's how he do. But with bits of pieces of events kinda fading out from his recollection.
glad to help
