So I've made it clear I have no intentions for Lucky to be the permanent DM. However, for a plot idea I had in mind, it would require him and Lumina to have 2 litters together, although he could be overthrown the same day they mate the 2nd time. For those of you who wanted the position, what I think might work-
Lucky, who was just starting to feel like a worthy DM, the Willows could possibly get in a battle and a meerkat dies, and the male who will be taking over blames it on Lucky for not being there to protect him like he should have been. They get in a fight after Lucky attempts to fight him, and ends up losing and the other male tells him he doesn't deserve to lead a mob like the Willows. He agrees, and flees, but not before promising the male pups in his and Lumina's first litter he'll come back for them one day. However, the male who fought Lucky feels terrible as it becomes clear Lumina is pregnant, and the pups won't ever know their father, and steps down briefly, allowing the other male that was considered for the spot to lead before the other one takes over for good.
This way, Kir Royale and Tank could both have time as the dominant as you both wanted the position.
For the plot I had in mind with the 2 litters
In the first litter, I'll have a male, probably named Danny, who is shattered by his father and role model leaving. When the next litter is born he decides to become like a father figure to them although he's only about 2 1/2, 3 months older than them. She'll grow closest with the female I have in that litter (Her name will either be Charm, Gracie, or Ariana, not sure yet) and eventually Lucky will return for his sons- but Danny will refuse to leave Ariana/Charm/Gracie as she's supposed to be very fragile.
