Sorry about that, this is how I think the characters will react:

1) Arthur: The one I am most looking forward to. Obviously he will be in a severe shock at first but later he will be extremely angry with Merlin for not telling him the truth. I think showing Arthur learn that Merlin poisoned Morgana and had a part in her corruption as well as Merlin's magic will add more depth to the story and Arthur would banish Merlin from the Kingdom as a result. Arthur would only forgive Merlin if the Kingdom is attacked in his absence, making Arthur realise how important Merlin has been to the Kingdom.

2) Morgana: Like Arthur, she will be in shock at first, but unlike him, she will then react more violently, even worse than her outburst in The Darkest Hour: Part 2, (saying things like "HOW COULD I BE SO FOOLISH" or "I WILL KILL HIM, THAT TRAITOR") she will see Merlin as a traitor to the Old Religeon, and if she learns that he is Emrys, she will want to kill him or expose him to Arthur as a plan to get rid of him. She would also target him more than Camelot itself, and I doubt she would even forgive him, unless she later redeemed herself.

3) Gwen: Now this is a difficult one because she may be shocked and perhaps angry but she might not be as angry as Arthur and Morgana because she doesn't quite see magic as complete evil like her husband does, but she probably blames it for her father's death partly because if her father never worked with a sorcerer (Tauren), he wouldn't have been excecuted by Uther. But she will perhaps forgive Merlin more easily than Arthur because she is not much of an aggressive person to harm Merlin.

4) Knights of the Round Table: I don't have much to say but I agree with the points you have mentioned Chris. Gwaine would accept it, Elyan and Percival would be a bit weary and Leon would be a bit angry and conflicted.
