Blue Bloods Season 10 Episode 2 revolves around divided loyalties.

When a store owner with ties to the mob is killed and the victim's daughter disappears, Danny and Baez turn towards a retired mobster that they once put into witness protection for help. The girl, Angelica, was the only witness to the murder and her life is in danger.

With Vincent's help, Danny and Baez find Angelica, but she won't talk and enlisting Vincent's help backfires when he advises Angelica to keep her mouth shut so she can have a decent life.

Meanwhile, Eddie and Jamie fight when Jamie is assigned a decoy operation that Eddie wanted, but later Eddie admits she isn't really mad -- she's just worried about Jamie. Jamie must pose as a cab driver to try to catch a guy who is robbing cabbies at gunpoint and has killed at least one of them while Eddie watches from afar.

And Frank and Erin again butt heads when the DA's office refuses to allow a cop to testify and Frank learns that some cops are on a blacklist because they had credibility issues in the past.
