User blog comment:LokiIsAwesome/Agravaine and a few other Series 4 characters.../@comment-5220958-20120813101103/@comment-5139779-20120813122222

To be honest I think Agravaine should have been introduced in The Wicked Day, appeared in His Father's Son and A Servant of Two Masters before being killed by Gwaine in The Secret Sharer. It would have kept his character simple in terms of the amount of screentime and a lot more likeable in which being a villain. While giving Gwaine a more significant role in Series 4 as being to one to kill Arthur's uncle.
