As for this topic, if they are showing a climatic duel between Arthur and Mordred, I bet Merlin will disable Mordreds magic like what he did with Morgana in the Series 4 finale, because Arthur would not stand a chance against him if Mordred can use his magic. Mordred seriously has to return in Series 5 because the biggest threat to Arthur and Camelot needs to rise.
