Mostly because Gaius is MY FAVOURITE FOREVER AND EVER and Uther is a dick

It's the eyebrows, isn't it? It must be. His are eyebrows of doom! love Gaius so very, very much. I was so sad when I thought he died in the first season. Like, noo! Gaius! Just let Hunith die! (I like her and all, but I just like Gaius way more).
