The best way to get rid of the extra brackets is to delete the (1), (2) in the episode title and not add the brackets. Then they should link properly. So this: [[Mystic Fate]] (2) should be changed to simply: Mystic Fate. If you're editing the cast and there is more than one person who played a role be sure you change cast to casts (notice the s on the end). Otherwise there will be extra brackets there too.
