@Rainbow: Interesting theory but mostly I think it’s a continuity issue. They just don’t care to make anything consistent. Like Anna and Hans and Kristoff NOT shattering to bits when they got Frozen
Actually i dont think is a continuity issue, on the Frozen area, they will probably say that the amount of power or emotion used, was not enough to shatter them in bits, this will be explain on twiter or in some interviews.
About Hook i think they did it on purpose, to show him as a match to the savior, and that they are TL, bc of that his love for her took away all the black spots, or whatever, this will be shown on the show, bc they need to keep the fan service going.
