Apologies to Robert Jordan. I own nothing but a twisted mind.
They had told him 'opposites attract', but he wasn't so sure it was true.
After all, he and his love had a lot in common:aesthetic perfection, a penchant for the color white, and an all-consuming dedication to their respective moral codes.
Therefore, he thought it unsurprising that she had compelled him from the moment they met, drawing him like iron to a lodestone. (Perhaps such an analogy belied his point, but 'flies to a midden' would have been quite untrue.)
And surely, wasn't it obvious to everyone that Lanfear and Galad were much more alike than they were different?
