Theory of Everything is the fourteenth episode of Clannad. The episode was first broadcast in Japan on 17 January 2008, and in the United States on 7 June 2009.


Kotomi finally leaves the house to find that Tomoya worked in the garden all night long and had fallen asleep. When she returns to school, Tomoya, Kyou, Ryou and Nagisa are all waiting for her. The mysterious stranger whom she was so frightened of, believing he wanted to steal her parents' thesis, is there as well. Kotomi and her friends find out that he is her legal guardian, and that there never were any written notes for the thesis after all. The stranger also has a birthday gift for her: her parents' suitcase, which survived the plane crash and was passed from hand to hand for years until he found it. Inside is a teddy bear, Kotomi's gift request to them before they left, and an affectionate letter, but no thesis. The stranger explained that her parents threw away the thesis to make room for the bear. He also explained that Kotomi burned not the copy of the thesis, but a catalog for bears, further strengthening her parents' love for her. While Kotomi is holding the bear, the room fills with lights, and she, at last, makes peace with her parents' deaths.
