User blog comment:Dryuuu/Why didn't Morgana tell Uther about Merlin poisoning her.../@comment-141.0.10.107-20120320140545

I got that from the episodes. ever since the series started from series 1. watch and listen to the merlin series very carefully from series 1 to 4 and you can see that merlin and morgana love each other very deeply but do not want to go pursue it. the love they have for each other is strong and it is the reason why morgana forgave merlin of the poison if you watch series 3 deleted scenes and did not tell uther also that merlin poisoned her because if she had told uther, then merlin would have been executed at once. she did not want merlin to die and she has never wanted merlin to die. she loves him. they both love each other.
