She was beautiful, of course. She took that from her mother, with help from her hobbit side to fill her out nicely in all the right places.
But she was more than that. He could have the kind of talks with her he'd only ever had with Merry or Frodo. She made him laugh until his sides hurt. She made him want to weep with joy when she was shuddering beneath him, crying out his name. She loved his son like he was her own.
Every day, he thanked the gods that he had her.
