It is ridiculous how much I love this. I've always maintained that Merlin characters are perfect for AUs, because you can sort of throw them anywhere and they still work, but they work especially perfectly here. Especially with the Morgana vision thing. And I totally believe her as the one who left the family to go to uni. Also, just out of curiosity, is she a biological or adopted sister in this? Like, maybe the daughter of another hunter who died working a case with Uther when Morgana was a baby so Uther took her in? And then later she is going to find out that Uther actually got her father killed like John Winchester got Jo's dad killed and then there will be angst? Maybe she doesn't even KNOW she was adopted and there will be angst over that as well?

In conclusion: write more.
