So I just watched episode 18. Basically the whole thing is over. Nagisa is back in school and the other girls realize that they have no chance with Tomoya. So now the race to win Tomoya's heart is over. Tomoyo will activate the Drama Club and Nagisa will be happy. Then of course Tomoya and Nagisa will get together.
Good episode though, Ryou and Kyou crying was quite sad.
