Quote 1, perhaps M was talking to herself, or thought Arthur was aware. But you're right, M was suppose to knew that Emrys, since The Wicked Day became an enemy for Arthur.

Quote 2 : M was very upset. What else could she possibly said ? It's just the scream of denial.

Q3 : Nothing to say about this one.

Q4 : Good point ! You pointed one of the many plotholes in Merlin. But I think it's not irrelevant, just unintelligible, as in the tears of UP, Morg. said to Merlin that she would have done the same (poison her), then how could she not question the knowledge of Merlin : How Merlin did he know she was the source of the magic ? You pointed out, in my opinion, the major hole of the series. The price to pay for keeping secret Merlin's magic is the stupidity of Morgana, as well as the stupidity of Arthur and the others.

Q5 : Merlin stood all night long beneath his masters, is it really irrelevant that Arthur said he was a loyal friend ? Arthur just lost his father with Merlin on his side ; is it really the wrong place to acknowledge the true friendship ?
