User blog comment:Dryuuu/Why didn't Morgana tell Uther about Merlin poisoning her.../@comment-4879894-20120318172759

The poisoning thing is one of the biggest twist of the whole series. It was a stunning idea. But, perhaps the writers didn't know how to manage it in the following episodes. There were other options that could have been chosen. 1. Morgana tells Uther and Merlin has to escape. The Wizard must look after Arthur and defeat Morgana's plans from outside Camelot, until the truth is revealed. 2. Merlin succeeds in convincing Arthur that Morgana is treacherous and Arthur succeed in exposing Morgana to his father. Morgana must leave and attack Camelot from outside, like she does since the beginning of series 4. 3. The writers have chosen the most difficult solution, perhaps the most interesting.
