I agree most of the woman are just [TARGETS] for Hunter and Drew. But I will defend Amber, Kumiko, and Eva as important additions to the story, maybe Aliza too. Amber is the reason Sterling can still workout after breaking his dick and arm, and now Kumiko is a convenient way to fix his hand and maybe his dick too
. Eva taught sterling how to have good sex. Aliza has a house Sterling can live in maybe, I do not know, we will find out later. Okay back to the main points: Aunt Keira and Grandma. why would Sterling invite them back into danger, so he can do better than his dad? He is currently protecting 4 family members and 7 more side chicks, why add two more. They aren't reliable as they already fell to temptation, and we don't need to give Hunter anymore help. They will be best left off until almost the end or epilogues. Don't get me wrong I think the model for Aunt Keira is hot, but not needed.
