User blog:Chawk1993/Gwen and Elyan's relations?

I was just on the front page of the site and I saw that on the new feature that is a shuffle thing (like on mp3 devices) that Gwen and Elyan's father was featured and on the roll down description it said that it was hinted that Tom's relations were hinted to be explored more in Series 5. Do you think this is correct and if it is who do you think will be mentioned (or seen)? I think it would be nice to find out what actually happened to Gwen and Elyan's mother. I know what Morgana said in an earlier episode back in Series 1 if I remember correctly, that Gwen (and Elyan) were now orphans because of Uther's unfair execution of Tom but it might have been incorrect information at the time seeing as Elyan wasn't introduced until late Series 3, like Gwaine was. I think, it would be nice to have Elyan and Gwen have more backstory other then the fact that they were children to a blacksmith and his wife. What do you guys think?
