I did really like Merlin in this episode but he was a bit of an idiot, especially when he went to Nimueh at the end and was all like 'I traded my life for Arthur's, not my mother's' (or words to that effect) and I was thinking 'um, no, she almost explicitly told you that she wouldn't take your life, you fool'. Besides, it never actually occurred to him to just ask whose life she'd take. *sigh* Not Merlin's finest moment, love and adore him though I do.
Thanks, glad you like it! :D
