Also, what episode does kirito tell Asuna he wants to be with her forever? I know that it's after they make it back to the real world but do you know what episode that might be in?:o

Well in episode ten, “Crimson Killing Intent,” he tells Asuna that his life belongs to her, until the end. That’s also the first time they kiss, and when he suggests they get married. After that there are a lot of instances where Kirito proves his love for her, especially throughout the alfheim arc. In SAOii, in the final episode he mentions again about wanting to be with her forever.
