What they may plan to do for the journey will not be easy and simple.

I thought they explained in the episode that if Emma and Killian share a heart then no one has to die for him to be revived.

But obviously the fact that they are explaining this before 5B even starts means that things aren't going to work out so easily. A bigger sacrifice will probably be needed besides Emma just sharing her heart with Hook so someone will most likely die.

It's most likely going to be way more complicated than sharing a heart and leaving the UW.
