|So I guess that Alvarr/Mordred/Morgana reunite and plot against Arthur/Merlin which leads to A/M eventually killing Alvarr and Mordred/Morgana have a further reason to hate them and seek revenge all season through? I hope there's something more to it. And I want to see how TPTB are gonna get away with Mordred knowing that Merlin is Emrys and not telling Morgana. Maybe all that he is aware of is that Merlin is known as Emrys between the Druids but since he's always referred to him as Emrys, I guess that sooner or later it should slip out of his mouth.|
Who knows, maybe Morgana will learn about Merlin being Emrys and indeed let Arthur know, but he simply won't believe her. Like when Merlin tried to tell Arthur that Agravaine is not to be trusted. Or maybe it's like in season 4 and nobody will ever tell anybody anything without any reason or because of the typical "they wont believe it anyway".
Alvarr and Mordred, the festival of returning baddies. I don't know... (supposedly) Good vs Evil is so not fascinating. Especially since Alvarr had worked against Morgana before, so chances are good that he might try to use her again and then it will be everybody vs everybody.
