Lithium is a gifted, magical toddler. He’s mastered the art of blinking - the ability to go from one place to another, in a moments notice. Using this gift, he reunited his parents, who had ended their relationship before he was born.
First, he blinked to Racolo, at Magick School. Then he blinked to the home of the Lady of the Dog, where Es lived. Racolo came looking for him.

When Racolo and Es saw each other again sparks flew, but not in a good way. Es felt Racolo had abandoned her. Racolo couldn’t forgive her for keeping her pregnancy a secret from him or for becoming a vampire. It took them a long time to get over their issues, and now they’re happily married. 

A Nanny

Cammeo was Lithium's nanny. One of the reasons Racolo first agreed to stay with the Crew was due to her loving care of his son. She also was instrumental with helping  Es become comfortable taking care of him.
