I don't understand the cousin thing, why is it a problem? In most countries, Sweden included, it's legal to marry a cousin. Even in many (about 20) of the states in US it's legal. I had a thing with one of my cousins when I was younger, even if nothing serious happened. Not because of a cousin problem, because we realised we were more friends than a loving couple. The aunt I can understand, their is the blood band stronger. So for me is that part of the story so bloody funny, even a little stupid.
Then I hated that I couldn't stop Lauren even if I did everything to insult her.
