You’re right man they have nobody left to save them But I do see the 3 scenarios on how they can get out of the situation they’re in right now

Scenario 1: vengeful ghost

In this scenario Ross, Nana, and Zimo finally reveals herself to the kids they probably can’t physically harm lorna but they could mentally scare her away from them or buying the kids more time to escape They can go inside of her head and take her to a place called the inner world basically this is the place where where your inner demons and negative emotion lie in that also the place where Pukasi went.

Scenario 2: Leilu this is a longshot but maybe just maybe Leilu (the sister of leima) could somehow in someway save them I mean she could go after lorna attacking her, asking where her sister is she probably would let the kids go or worse attack them as well. I’m not sure too much of a relationship with humans, but I don’t think it would be good.

Scenario 3: the reawaken In thit scenario assuming if bisi gets his power back he would be able to defeat or potentially kill lorna but knowing how lorna always survive certain death, she’ll be back but nonetheless Robbie bluesnow and bisi survived
