Cerberus, Lupin's Houndour, looking rather anxious and for reassurance from his trainer. Whether it's from an itch to jump into impending fight or from nervousness, it's hard to tell. Maybe both. Lupin knows he's got what it takes, however. She believes in him.

Cerberus, in my head, is a bit of a spitfire, with no pun intended toward his type. He's eager to please, protective and loyal, but a little rough around the edges with new people. However, with a few cues from Lupin, he takes her lead in warming up to newcomers. Lupin sees great potential in him and, admittedly, can't wait to see him evolve and expand on that potential even more. She's also grateful that, like Amaroq, he's patient with her pup and sees her as a fellow "pack member" instead of a threat for attention.

Cerberus, obviously by the name, was dubbed so after the Guardian of the Underworld in Greek mythology, who prevented those who have entered from escaping again. He also apparently only liked living meat, so spirits passing through were safe from him.
