I too think that he will appear as a ghost. What else? According to the interview with Johnny Capps, Uther will have a "long overdue" conversation with Merlin about Arthur and it will be very emotional. Does that mean that Uther knows about Merlin? And what could he possibly talk about with Merlin regarding Arthur.... maybe Merlin lectures him or maybe, which I hope, Uther had known about Merlin and the entire destiny-thing the whole time??... I'm very curious! But I'm also, as usual, very pessimistic because I fear that they will make Uther being the stubborn man again who needs Merlin to open his eyes when he tells him that he is responsible for each and everything and whatnot. I hope I'm wrong about this.

It has also been said that Merlin will feel Uther's presence when he is talking to Arthur. I guess Merlin will be able to summon him from the world of the dead and later gives Arthur the opportunity to talk to his father, maybe even through him in case that Merlin is the only one who can see Uther.

On the other hand, the very "unexpected way" that he returns might be that he actually isn't dead?... That would be awesome! But I doubt it. But if he is dead, which certainly seems to be the case, is he now reunited with Igraine or will they ignore the whole Igraine/Uther-story again?

Anyway, here is the link to the interviews: http://www.threeifbyspace.net/2012/07/comic-con-news-merlin-puts-a-spell-on-viewers-for-season-5/
