They are annoying and will only risk making another annoying filler episode like Lamia. I think their appearance would be irrelevant, unless they could find an elaborate way to fit them in with a plot which will get the story going, but... they're meant to be immortal, having lived for thousands of years, and it seems they don't even know the destiny of Camelot and Albion. I'd like the Lake of Avalon to appear again, and Morgana to die in there like you suggested, sounds like a good possibility, but won't that give the audience the idea that Morgana will become a Sidhe? For me, that would ruin it. A blue Morgana with wings? No thanks. They should cut the Sidhe thing out, and just use the Lake of Avalon for another portal for a human death. Another note, if they're going to make Morgana regret what she's done, they're going to have to do a damn convincing job to make the transition from the stereotypical, one-dimensional homicidal, psychopathic, and sadistic personality she has grown into, to the loyal caring character who does what she knows is right that she was at first. Should this transition happen, it should definitely not happen in a matter of minutes- maybe a recurring element throughout the series that constantly reminds Morgana of just how corrupt she has become, that is slowly creeping up on her, until she finally snaps.
 * I agree, more characters, location, magic (more spells other than stunning) and creatures! I think we're getting two new creatures in the opening, thank heavens.
 * I wonder who would have taught Mordred? I didn't think a group of dark priests would exist at this time, since Uther killed most people with magic, and also, it would be too much of a threat for Merlin.
 * I really hope Lancelot and Freya make another appearance! They're an important part of the legend. I don't know about Uther, though, what importance could he -possibly- have? A moment where Arthur reunites with Uther in spirit.. what would he have to tell Arthur?
 * Gaius's death- Yes, he does need to die, just because of what it will do to Merlin's character. It WILL change Merlin permanently, and possibly make Merlin more likely to reveal his magic as Gaius won't be there to tell him not to. Plus, the dragon has foretold of Gaius's doom for some time. Early or late (preferably early-in the middle of the series), his death would be a great twist for the show, despite how sad it would be!
 * Kilgharrah dying would be a great twist. Maybe at the end, a final blow that destroys the enemy and Kilgharrah at the same time.
 * I disagree with the Phoenix idea, I don't think anything should precede the Dragon in power, mainly because, if they introduce a being more powerful than the Dragon in Series 5 (The exception of The Cailleach was fine), it will make it seem more unrealistic, as it's never been mentioned before. It will just seem like they're piling more stories on top just because they can. I may be wrong, though, but I'm skeptical about an episode where: Merlin: "What's that giant red bird in the sky? KILGHARRAH! STOP IT!" Gaius: "Oh no, it is the phoenix, a being more powerful than any dragon!" Merlin: "But I thought dragons were the most powerful around. How come we've never seen it before?" Gaius: "Because Gilli released it!" Merlin: "Well Gilli's a c$%!." Then Merlin goes and kills Gilli. Sorry to degrade your idea, but I know it's just an idea and we see things differently.
 * About Kilgharrah deciding whether he stays loyal or not, and deciding to stay loyal, wouldn't that be pointless, considering he cannot disobey a dragon lord, their souls are bound together, he hates Morgana, and he wants to see Albion built and magic restored... which I don't think Morgana can do a good job of. That would seem like a cheap way of building suspense.
 * You've mentioned the flashback episode several times. Merlin's never used that sort of technique to explore stories before. It sounds great for a movie, but would it fit in the TV series? Only they can make it work...
 * I definitely think Lot should appear. He was mentioned in several episodes, by Tristan, Arthur and Morgana. (She was talking to Helios and asked for a message be sent to his kingdom, that there'll be an award for Arthur's capture)
 * The Sidhe? PLEASE GOD NO.
