''And Uther conceived Morgana when Gorlois was at war, so why didnt he knotice that his wife was pregnant even though he wasnt there to ... you know, do the deed at the time?''

Who's to say that he didn't know? Given Uther's certainty that he is Morgana's father, the date range for her conception is likely to have excluded Gorlois as a possible father but Gorlois may have decided against denouncing his wife for adultery, and been willing to raise baby Morgana as his own. Alternatively, he may not have wanted to know, if he wanted to continue with his marriage, and preferred to believe that Morgana was strong and healthy for a premature baby, or that she was a few weeks overdue.

''4. Aithusa helping morgana makes no sense. Unless the conclusion we should make is that the great dragons prophecies are bunch of poop. After all, he said that Aithusa was going to be a GOOD omen for Albion, plus his name means light of the sun. How do you go bad with a cool name like that? cough... Anyways... What do you think?''

Kilgharrah's prophecy about Arthur was never realised, which means that it wasn't the only possible future. Perhaps Aithusa saw a different future, one in which Morgana would go on to do great things, and wanted to protect her. Morgana was told that she was destined to restore the Old Religion - which she may have done in death, at least to an extent - but we don't know what Aithusa may have seen in her.
