Katie’s journey as an actress has been rather parallel with her becoming the powerful priestess Morgana.

She explains about her journey as wandering princess to a confident sorceress, and how she considers herself lucky to have been a part of the cast for 5 years.

She’s pleased with how the series has ended as she says each and every character has told everything that can be told and the final two episodes will wrap up all the questions quite nicely.

Katie looks up big time to Colin Morgan and explains that he is far beyond the rest of them. “But the problem when you’re doing something that Colin has already done so wonderfully and brilliantly before you is that you feel you have to live up to it. I’ve learnt many years ago not to try to live up to Colin Morgan – there’s no point, he is on a level that is far beyond the rest of us, so it’s better just to have him as your goal and silently plod along behind him!”
