she has been going through the same painful cycle of his memory loss for THREE YEARS. Telling the same story, going to the same places. Even Tomoya got tired of her asking about it at the end of the week, yet she did it every 10 days with a smile on her face.
Also, I finally playing after 100%ing the original Clannad and AS back in 2008 or so and reading the Tomoyo After manga around then (because Tomoyo was my favorite character), so I sort of knew what type of ending to expect. However, it does seem like he just has a speech and walking impediment, and he's starting to recover. I didn't get the impression that he dies, which would be too sad for Tomoyo
All because of that damn rain in the village! So what makes people think he died?
