When Emma picked up the dagger and absorbed the darkness, she became tethered to the dagger/now sword and became the DO. And now that Killian has been tethered too the sword, he is a DO too. Then  Merlin got tethered to excaliber by Zelena, and he was seemingly subject to the darkness (I assume this because Emma said something about him resisting it when the vine strangled Snow).

So, was Merlin actually a Dark one for a while there?
