It would make sense for Percival to deliver the news. The thing is though that if Merlin is immortal then how to did he grow from a kid to a man and to an old man? And what was his true form in modern-times? He has magic, wouldn't it be kind of realistic if he could change his appearance from old to young and the opossite using it like he did with Dragoon? Because if he just stays old even when Arthur arrives again it would be lame. But, it would also make no sense ageing while being immortal.

An explanation should follow this finale because if what you said is true and we don't have a way to learn the truth we will be confused forever. There should be made some interviews with the producers and actors to explain some things.
