One сказал(-а) that emilia лиса, фокс is not returning to merlin as she сказал(-а) in an interview that she will be doing another tv season(probertly silent witness).
But this is not true as we have seen pictures of her filming season 4 with katie.
I also founds out that Nimueh, Morderid and alvar will be returing,along with lady vivian and Elaina.
They are also going to introduse еще knights of the round таблица yay.
