So I was thinking, did Merlin take into account that Emma will be a Dark One at his point? I mean, Regina says it at one point, "sometimes spells are like snakebites, you can make antivenom from the venom." So what if one of the conditions to free Merlin was not just the tear, but also that the one to breaks the curse is also the one who cast it, i.e., the Dark One (and not necessarily a specific Dark One)?

Also, possible that Nimue is the one who trapped Merlin? Considering he couldn't kill that Dark One.
