Queen Amanda married Adrian a few days after their return to Raz, much to the dismay of the available young men who had eagerly sought for her affections. Her parents remembered the Infer and were happy to welcome him to his new home.
Jake decided to invest his money into helping orphans by establishing caring homes for them to grow up in. He married Katherine, and they remained in Louisiana. Katherine realized that the Great Magician was right and her home wasn’t to be on Raz; she belonged on Earth where she could do the most good. Jake and Katherine often visited Clark.
As for Matthew, he found Cara was a delightful companion after all and married her several years later.
To quote an old and familiar phrase, they all lived happily ever after.
