In Season 4 episode 1, in Morgana's vision, a battlefield could be seen full of dead knights. Emrys was there, and when Morgana asked his help, he merely asked her if that's what she wanted from the beginning.
Most of you probably know that if you've been watching season 4. This is likely to happen in the battle of Camlann(I hope it's written that way), the final battle of Arthur, which probably is a long way from season 4. Considering than Morgana's dreams almost always come true, why is it that people think she will die this series or, if not, some time close to that? She is an important part of the legend from the beginning to the end, she can't just die off in the middle of it.
Also, when this vision comes to pass, what do you think will happen? Will Merlin kill Morgana for what she seems to have caused or not? What I think is, he will orded her to go to Avalon and heal Arthur, or maybe Arthur will ask him not to kill her, since she is his sister and he forgives her. Either way, I think we will have Morgana repent for her crimes and sail along with Arthur to Avalon. And maybe Merlin will go along with her, in order to prepare Arthur for the future when he is going to be needed again to protect Britain. For me, that's the most suitable Merlin ending that I've thought of. What do you guys believe?
