User blog:Morganaforever/Arthur and Morgana

I've been watching season 1 of Merlin and I noticed how Arthur and Morgana used to flirt in front of everyone. Since Uther knew he was the biological father of both of them, what kind of SICK dad would be happy to see his two children get romantically involved with each other? For example, on 1x02 when Arthur defeated his enemy, Uther was glad to announce that Morgana will accompany Arthur to the celebration.

That's why I think that it was originally planned out to not have Arthur and Morgana be blood related.It just doesn't make sense in season 1. This idea must have came up in season 2 or 3, when the writers needed a reason to bury the Arthur/Morgana romance completely, so that the Arthur/Gwen romance can bloom. What do you think?
