Marshall's Links
Emotionally and psychically bonded to her almost immediately. Once they realized how they were connected, he became her closest ally and would rip the world in half if it meant keeping her safe and happy.
Likes to try and mess with him. It never works because he's stupid strong, but he's amused and she has fun regardless. Adores him so much. Makes jokes about him being her younger brother, which are *technically* correct.
Technically her son. He's never actually met her before, he just knows that there is a being called "Mew" that he's directly based on. He has no idea how he would feel if he ever met her face to face.
Technically his mother. For most of the story, she has no idea he exists - once she learns of him, she decides to watch him from a distance and make sure he's okay while staying out of sight.
