Mad Max: Furiosa's Sister

What if Furiosa had a younger sister? What if that said sister rode alone with her on the War Rig?
Jordan is a short girl maybe 5'0", roughly in her mid 20's hard to keep track nowadays, green eyes, always keeps her long brownish black hair in a braid down her back, and can almost always be found in her boots, ripped jeans faded over the years, black tank top, and when in the War Rig a black vest over the top of it all.
When Furiosa and Jordan decide to leave the Citadel with Imortan Joe's breeders, they run into trouble and end up with a crazy man.
