User blog comment:Fimber/Things that went wrong in "The Death Song of Uther Pendragon"/@comment-4892425-20121023020718/@comment-5102537-20121023103037

@It's Good to be Queen - he had already known about Morgana's powers at the end of season three. Even if the deleted scene is not so relevant for the original epsiode (if so), he saw what Morgana did and everyone else knew that she has magic. Uther was a prisoner for a week with view to the court yard and he could also hear what people were saying outside. Then, the year before he died, he was informed by Arthur about everything in Camelot every day and since everyone knew about Morgana's powers, Uther knew as well.

I see what you mean but the example above is what I dislike on that show. It is meanwhile about hurting others and seeing it all black & white.
