In 4B we saw Gold's heart was like dying or something because all of the darkness. He showed her heart to Belle and explained it. Even more, in the finale, he passed out and the Apprentice had to remove the darkness from him to save him.

BUT

and the end of 5A all the darkness returned to him when he became the Dark One again. And the darkness was even more powerful because he has now Dark Swan and Dark Hook power inside.

If the darkness in his heart was killing him in 4B, how come he is prefectly fine now?

How did that happen?
