SFX: Your character knows “Emrys” is going to be her downfall. Do we discover more about that in this series?

McGrath: He’s a very large presence to her. She doesn’t know who he is but he is a very fearful presence for Morgana – and a driving force for her throughout series four. It’s a big deal, that Emrys problem! Her need to discover who he is and ultimately vanquish him is a big part of what she does going forward. But I think she believes she’ll get there in the end. She doesn’t know who he is, just that he is out to get her and that she could ultimately be destroyed. (x)
