Besides, it is clearly somewhat different, as the smoke was different from what we have seen everytime the Dark Curse is cast. So long story, short: It's not the exact same curse, so it doesn't need a heart.

The smoke for Hook's curse was different from Regina's, and so was Pan's.

Regina and Snow: Black with shades of purple and green lightning.

Pan: Green

Dark Hook: Vibrant purple with yellow lightning.

Black Fairy: Black
