Fire Country: Sharon’s mother Ruby arrives in town

In an unexpected twist in the story, Sharon discovered that Vince was paying off money to someone on Fire Country season 4 episode 6. Titled Your Voice in My Head, the episode presented an irrational Bode wanting to investigate his father’s death. 

Bode’s moves tended to be imprudent since he forced his mother to get him signed up for the investigation. Moreover, he tried to overstep the federal agents and even threatened Agent Ruffin to continue with his parallel investigation if she didn’t heed his tips. With this, he created trouble for himself, Manny and his mother, Sharon.

Meanwhile, Sharon learnt that her mother was blackmailing Vince before the latter’s death. Rummaging through records and files, Sharon reached Walter. After treating the latter with a nice lunch, Sharon got down to asking for information about Ruby blackmailing Vince. Walter revealed that Vince paid off Ruby to stay away from Sharon. He feared Ruby had a negative influence on Sharon after Riley’s death.

Walter also disclosed that Vince knew his son was dead when he forced Sharon out to save her. Moreover, he clarified that Vince had also passed away before they left him, leaving Sharon free of guilt and remorse. After learning of all the truth connecting Vince and Ruby, Sharon decided to inform her mother that the blackmailing payouts will stop, now that Vince was no more. However, before Sharon could follow up on her decision, Ruby arrived at her daughter’s place, planning to stay for some time.
