Morgana had two modes: Evil and stupid. In the next episode she gloats that Arthur's weapon cannot kill her (although it can, but consistency and pay off are foreign concepts to these writers), presumably because she is a high priestess, and hence, immortal. Her troubles and tantrums would have ended sooner, if she had used the abilities bestowed upon her as a high priestess to just kill Arthur. Nimueh could summon and all kinds of creatures and do all kinds of things remotely. Why couldn't Morgana just kill Arthur, and thus take the throne and prevent her vision from happening in the first place?
