One possible plot could be Leah dealing with the reactions of her pack. Some might be supportive, while others could be judgmental at first. She'd have to navigate her changing body and the new responsibilities that come with expecting a baby.
It could be another werewolf from her pack. Maybe someone she had a secret relationship with, like Seth's friend who had always been secretly in love with Leah but was too shy to admit it before.
The plot might involve Leah finding out she's pregnant and then trying to figure out who the father is. If it's in the context of the Twilight universe, there could be added complications like how the werewolf nature affects the pregnancy and the unborn child.

One common theme is friendship. Often, the OC becomes a great friend to Leah, helping her through her tough times, like dealing with her wolf - related issues in the Twilight world.
I'm not entirely sure as the 'grunt story' isn't a widely known mainstream narrative. But generally, Leah Clearwater and Jacob Black are characters from the Twilight series. Leah is a werewolf and has her own complex relationships within the werewolf pack. Jacob has his own story arcs involving his love for Bella and his role in the werewolf community. Maybe in this 'grunt story' there could be some specific adventures or interactions between them that are unique to this particular telling.
