Yesterday, when Jacob said that he wanted Bowie Faulkner in the basement first, J became suspicious. It was not in their original plan that Bowie would be in the basement of the Twelve Army. After all, Twelve Army is not involved with Bowie.
Then J found out that Jacob allowed Damien Roald to talk to Bowie. That made her more suspicious.
J was in her office and just hung up the phone after talking to Nora. She just wanted to make sure that she is fine and as expected, her daughter was still whining. Nora wanted to be involved but Jacob strictly disagrees.
Nora thought that since she is going to be the next leader of the Robin Hood Society, why not let her do something? Why not let her participate? Jacob understands Nora's thoughts but as a father, Nora's safety is his priority. Not that he doesn't trust Nora or the Robin Hood Society, but he just cannot trust Bowie or Damien.
