i highly doubt it's either Rumple or Leopald because the Wizard said Cora gave Zelena up because Zelena couldn't make her royalty. This means no royal blood from Zelena's dad. And if Rumple was her dad, I doubt he'd have ditched her. But even if it does turn out to be Leo through a weird twist,who knows? Maybe it can work.
