Thank you for your thoughts and thatnks or agreeing that he should have appeared in Queen of Hearts! I think there should have been a reference to Elyan before his appearance, like the quote you suggested, the wirters could have made Gwen said, "Ever since my mother died, and my brother left, he's all I have!" And something I'd like to add, Gwaine's sister was mentioned in A Herald of the New Age whe Gwaine said, "my sister's an evil old toad," when him and the knights were chasing Elyan. So it's possible that she could appear in Series 5! And this time we would have a reference before appearance!
