Renesmee and Jacob will have a relationship as soon as Renesmee is fully grown. How will their relationship work with the fact that Renesmee will never age further and live forever but Jacob will grow old and die since he is a werewolf?
As a werewolf, Jacob also has the capacity to stop himself from ageing. 늑대인간 don't age while they're still shifting, so all he'd have to do is keep going into 늑대 form regularly. The other 늑대인간 just eventually chose to stop in order to age with their families, 프렌즈 and imprintees/partners.
