And Rumple says that if they (him and belle) dont manage to stop him, war will come to SB. I guess it could work like the DO, (I guess Gideon wants to live up to his namesake as being the hero), but......nevermind.

There is stuff sort of preceding it, like how Emma couldn't even put her heart into Hook's body (likely impossible with a DO heart). Plus, it could be like the Dark One's curse, where the Dark One loses their light, the Savior loses their life.
