So it seems Emma is meant to get the ball rolling for breaking the curse, but seems Rump’s is indicating more that she will be there to start & fight in the ‘final battle’. At this stage I think the actual breaking of the curse will be someone else’s actions rather than Emma’s per say (she’s the instigator & will get them to the point where they can do what they have to do, but its their actions not Emma’s that actually break the curse) if that makes sense.
Yes, that’s what I’ve been saying all along! In the 2nd episode Rumpel also tells Regina that Snow’s child is the key, but never actually says she’ll be the one breaking the curse.
