I agree with the idea that Maleficent lied. I find it hard to believe that she mated in dragon form without ever seeing who he was. Also, in 4B we never got a full backstory of Maleficent (how she became evil, what changed between her and Regina, etc.)

Maybe the reason the writers didn't do this was because they had something planned for when it came time to go over Lily's father. As for the King Stefan idea, it's possible.
