We don’t know if he is immortal still…he was frozen in time like everyone else for 28 years but now that time is moving again he could be aging. We have heard people say he was immortal…Emma told Hook in the hospital for example but do they know for sure? If he is still immortal and still the Dark One then why didn’t Belle’s kiss break that curse? They have kissed since magic was brought back. So technically, he shouldn’t have those powers anymore. Is it possible that he is only partially the Dark One? If so, which parts/powers? How does that affect the daggers powers…
