And whether they should have their own POV threads.
Does this story need dramatic irony or surprises? Because a new point of view needs to introduce information that the original does not know -- or we could just get it from the original and have the added bonus of less clutter. (Always use as few points of view as the story can stand!)
Except playing against that is even if the information can come in later, it's less likely to be dramatically presented. Being told the villainess had kidnapped the character, or having the princess talk about how she ran away from the same ball as the heroine attended, is not the same as seeing it happen. (Though, on the third hand, if I put in the kidnapping, it's not going to end with the place where he's kept captive, because I need that for a dramatic reveal later. Ah, juggling.)
I think it's going to be multi-POV.
