I really hope Gwen finds out. I think Gwen will take it lot better thenwhat Arthur will even if it means having to put her marriage to Arthur on the line. Yes, he's lied to her for so many years but I think in her mind, Merlin was her friend long before Arthur became her husband and I think she considers Merlin more important to her then Arthur to a certain degree. I'm not saying that Arthur isn't important to her, of course he is since you know, he's her husband and the King to the kingdom that they BOTH rule but she had a crush on Merlin long before she had one on Arthur and its obvious that our favourite Queen considers Merlin to be another brother to her and we know that Merlin loves Gwen like a sister. So I hope she finds out. Since she's now Queen, she will have a very difficult decision if it really comes to it having to choose between her beloved husband and her best friend who has been there through thick and thin for her. Maybe you're right, maybe this is what puts their friendship on the line.

I would love Gwaine to find out as well, we all know that Gwaine would never hurt Merlin as they are almost brothers. Eoin has even hinted at Gwaine finding out so I hope he does find out and takes it better then what Arthur will. I think Gwaine will be the first to defend Merlin seeing as they are pretty much brothers.

As for Morgana, I don't think she'll find out until its really late and if you think back to her vision of a battlefield with dead knights from both Camelot's side and the Saxon side (AKA the Battle of Camlann which as been hinted at this season), she pleads to EMRYS for help not Merlin and Merlin IS Emrys so I think there's a slim possiblity at that one.

The Knights of the Round Table will be interesting to see their reactions. I think since Elyan is Gwen's brother he will have take it well but as for how well I can't really be certain as he will be forced to choose a side if it really comes to it: Arthur or Merlin and there no way in hell that he will be able to choose as he's loyal to them both of them and he wouldn't want to get on the wrong side of Gwen either as its bound to come up that he wasn't there when Tom died and Merlin was so it may cause conflict there. Percival and Leon's reactions will be hard as they're more loyal to Arthur then what they Merlin since Merlin is so of the co-leader of Arthur's inner circle, then I would say they will be conflicted.

Now the whole issue with Mordred spilling the beans, I think he will threaten Merlin at some point to reveal his secret to Arthur and we don't want that as Merlin will have to be the one to tell him not the future murderer of his best friend and I think there might even be some blackmail involved.
