- Lupis had an eternal friendship with Luna since they were pups. Now since they've gotten older, they've only been driven closer together. In episode 24, Midnight said Lupis only had empathy for Luna, and felt sorry because she was the Omega in the Pack of Night and had no friends, and Midnight claims Lupis likes her instead. At that time, Fang made an agreement with Rune to let Lupis leave with Rune and his companions, and Fang exiled Luna for humiliating him at a meeting.
- Lupis is secretly a son of Balder--or so he claims--and he has secret relationships, but no one knows about his family.
