Play it again!
Yes, But you can't fight the boss again.
Probably not (if you noticed midna shattered the mirror of twilight, the only thing connecting the twilight realm to hyrule, in the cutscene after the credits of twilight princess), unless Myamoto decides to do a direct sequel to twilight princess, which isn't totally out of the quuestion; see "Majora's Mask".
In Twilight Princess, like most Zelda games, you are not able to save after defeating the final boss. This allows you to go back and complete any side quests you want and/or beat the boss again if you'd like.
Midna was Link's helper and guide throughout most of The Legend of Zelda: Twilight Princess (except for the very beginning), and is also Princess of the Twilight Realm. Zant (Ganondorf's servant) had turned her into an imp, and so to get back at Zant (and eventually, Ganondorf for destroying most of her tribe), Midna (in her floating imp form) had decided to help Link in The Legend of Zelda: Twilight Princess, because she knew that Link had the potential to help her tribe, and help her become Princess of the Twilight Realm again.
You can fight him as many times as you want.
go to the woods near the forest temple to go to the secret grove........ again
Yes he'll be playing Edward again YAY
Its a game where you can fight the final boss fight over and over again. This is in every Zelda game, and no one knows why.
you kind of find out during the story line that twilight princess happens AFTER ocarina of time ends, so he's a teenager or so.
Edward and Bella kiss in New Moon again in New Moon in Bella's Birthday.
As far as I know you can't. After you defeat the game and play that file again it starts you back to before you defeated Ganondorf.
