that's a really interesting theory,but I am pretty sure it was Morgana.Remember at the end of the episode she had a dream?Maybe it was because of this.Also,Nimueh hasn't returned and its almost the end of season 3
Hope I helped !
Morgana gets poisoned by Merlin in the episode titled "The Poisoned Chalice," which is the 4th episode of Season 2 of Merlin. In this episode, Merlin uses a potion to poison the chalice intended for Arthur, but Morgana inadvertently drinks from it instead. This incident highlights the complexities of Merlin's decisions and the unforeseen consequences they can have on those around him.
Well many people are still not certain whether it was a trance-like Morgana (in other words Nimeuh) or Morgana herself. I do though think that it is morgana trying to warn Merlin to be careful because she may of had another frightning dream like the one about arthur getting bitten from the creature which she did in the very same episode she warned Merlin in. She warned Arthur so now she probably was warning him because we know she cares for Merlin and Arthur. Basically, I really don't think it is Nimeuh because why would she warn Merlin about the dangers ahead. Hope this helped!
Katie McGrath plays Morgana in BBC's Merlin
In season 3 episode 5, she overhears it while she is sick.
It means Torren was able to make friends with Morgana and get her to do what he wanted her. It could also mean Torren made an assisstent, helper, supporter of Morgnana and made her be real enemies of Uther.
Merlin has a beard and Merlin is just a servant person thingy and Morgana is the kings sister so i guess they're just kind of nothing in laws.
In season 2 Merlin kisses a druid girl called Freya (in episode 9) who is played by Laura Donnelly. If anyone is upset because they wanted Merlin to kiss someone like morgana don't be so upset because freya (Laura Donnelly) only appears in this episode so they can't really have a relationship so there will be more time for morgana (if you want them to be together) or anyone else.
Merlin protected arthur, impaled morgana with a sword, forged with dragon breath, the sword we know as Excalibur, which in turn, in the end merlin through with back to the lady of the lake.
In the series "Merlin," there are several episodes where Merlin is hurt. Notably, in "The Poisoned Chalice" (Season 1, Episode 6), he is poisoned while trying to protect Arthur. In "The Coming of Arthur" (Season 2, Episode 12), Merlin faces danger during the battle against Morgana's forces, and in "The Last Dragonlord" (Season 3, Episode 5), he is injured while trying to save a dragon. These moments highlight the risks he takes to protect Arthur and the realm.
In the story Morgana kills him by a magical sword in the heart
...King Arthur
If you mean Morgana in BBC Merlin then she is his Ward. But in S3 we find out she is actually his daughter and not Gorlois'.
