You don't know Owain? He's the same character as Yvain.

If the name hadn't already been taken, I could have called my comic "Family Man". Gawain is very fond of and very protective of his family. If you see Gawain/Owain slash potential (mind you, Gauvain/Yvain is my Kaamelott ship, if only for fun), then I predict that you're also going to detect Gawain/Gaheris, Gawain/Agravain and Gawain/Arthur in the future :P.
