But if Drizella had Regina complete the ritual, does that mean that Drizella dying would do nothing and it would have to be Regina whose death ends the curse? (not that I'm remotely worried about her dying, as we know there are other ways to break a curse) We've only seen the caster die once before -- Fiona, and the curse was broken. Fiona's curse was also different, using fairy dust and destroying the realms, so it's not a great precedent, but it is technically a precedent.

Hook died after casting his curse, but the only effect was the memory wipe which had already been undone by Emma. So we don't know if that was broken or not.
