WHat I am thinking is that Sam is one of the scouts who discovers the mutants, and is the one who brings back the evidence to Vree. Thus the story of Maxson's scouts might be resolved.
I am thinking that after the rad scorpions it's off to vault 15. But perhaps Vault 15 is more alive than when the vaultdweller finds it.
ALso I want to rebuild the story of junktown, perhaps making Gizmo a good guy. Ideally, Gizmo and Killian where, at one time, partners, as well as the owner of the hotel who came a bit later. Killian began with setting up a trading post. Gizmo joined to set up a casino and bar. However, to make it work they needed currency- the bottle caps.
The Hub merchants so this as an opportunity to expand their business interests, perhaps in the process removing both Killian and Gizmo in the long run, but make an alliance with Killian in the short round. Gizmo doubted the Hub merchants but Killian believes them. Gizmo's plan then is to (1) rid Junktown of the Hub presence, and (2) upset an alliance between Killian and the Hub merchants, perhaps by making both begin to doubt the other's motives.
The conclusion of this will be that Junktown has more autonomy when the Hub presence is removed. But Killian will be afraid and never leave his building and has created a police to protect the town. He will also be at war with Gizmo, and have the upper hand, with Gizmo limited to using the random assassins and the local gang.
