User blog comment:Dryuuu/Agravaine and Morgana's awkward relationship/@comment-5036924-20120119182519/@comment-5036924-20120121150633

Doesn't really explain a lot, actually. It's fairly obvious that he's her "bitch"; that's basically the one fundamental thing about his relationship with her - that it's unequal and that he's her servant.

What's less obvious is why he has such genuine emotional loyalty to her. Is it just because he hated Uther for 'killing' his sister? Would he even know Uther's part in Arthur's birth anyway, since it was meant to be a secret? It's not really clear why Agravaine would be so anti-Arthur since Arthur is his actual nephew, the son of his presumably beloved sister, and he is also very clearly a good and fair king, which Agravaine witnesses first hand. I suppose he could just be an irrational troublemaker, yet somehow that doesn't quite fit with his character. It feels like he's got some real cause behind his actions, yet I can't pinpoint what it would be.

I can only surmise that he's got some warped obsessive love for Morgana which means he ignores the lack of rationality for hating Arthur.
