Reizy is incredibly jealous of Nava and how easily she allows herself to talk to Rubilax. That’s what this animation is about. Rubilax leaves, and Reizy is left alone with her thoughts; the puppies in her head start bothering her and pushing different ideas onto her. She’s pining for Rubilax and suffering, while Nava simply goes ahead and talks to him like a friend. Reizy would kill Nava if she could. Rubilax won’t let her kill her. And Reizy would never betray her master…
If anyone can kill Nava, it’s only Rubilax.
The wolf in this animation is the Spirit of the She-Wolf, which I’ve already written about under one of the artworks. The Spirit of the She-Wolf merges with the soul and fills the host’s mind with intrusive thoughts and ideas - things the host might truly want deep down, or what would be safest for them.
