It's just a thought. But since this arc is about closures and everyone we knew has to make one (the characters who are still alive), Merida might have to make one herself.

What do you think? Merlin said, that it is easier to live with the darkness, if you dress it up as vengeance. In the OUaT universe, the Darkness appears to be the manifestion of vengeace. Nimue became the first Dark One, because she murdered the man who destroyed her home. Merida is actually making the same mistake as Nimue, by seeking revenge on Arthur.
