What happened to you, Morgana? I thought we were friends.
DO YOU GUYS KNOW WHAT THIS MEANS?!
IT’S A SEED
A PLANTED SEED FOR ARTHUR!
Arthur will know the name Emry’s and be like
“Wait someone is trying to protect me?”
“This person has magic and they’re trying to protect me?”
So in Series 5 he’ll know the name Emry’s and probably be told stories from Gaius and Druids about what ‘Emrys’ has accomplished for him.
THEN WHEN THE REVEAL HAPPENS THERE WILL BE NO ANGRY ARTHUR
BECAUSE HE’LL KNOW MERLIN IS HIS GUARDIAN
