Of Children and Travelers

Walt and Vic investigate the murder of Polina, a young Russian teen whose adoptive parents traded her away to a couple they met online. This exposes a network of child trafficking, leading Vic and Walt to pose as parents of a troubled child. They learn Polina was simply trying to protect her younger adopted sister and was killed for it. Meanwhile, Branch returns to work but remains fixated on who shot him. Henry gets abused in prison by fellow natives, led by former reservation sheriff Malachi (Graham Greene), for his friendship with Walt. Malachi wants Walt to vouch for him at his upcoming parole hearing, in exchange for Henry's future welfare. Cady becomes Henry's public defender after firing the inept one assigned to his case.
