Aranel excepted a proposal from the Elven King only to get out of Rivendale, not for love. She didn't realize what it was like to be a queen or how cold hearted Thranduil actually was. She continued to try and change him but his refusal to move on from the past continued to drag her down further into heartbreak. Thranduil tried to test her and get under her skin but she always seemed to put him in pain from elbowing to spiting and biting. She was not his first wife, so why would he try? She married him for convenience not for love, but why can't she stop herself from getting feelings for him?
