Ep 9. Bad Blood

Danny and Baez investigate the murder of a college professor who was involved with a questionable scholarship program. Meanwhile, Danny learns that his father, Frank, didn't always stay on the straight and narrow. Jamie tries to convince Eddie to reconcile with her father. Frank confronts his archenemy, Mayor Poole, about a robbery that happened decades ago.

In the beginning of the episode, Jamie and Eddie are discussing their plans for the upcoming holiday. Eddie reveals that she doesn't have a great relationship with her father, and Jamie encourages her to reach out and try to make amends. Meanwhile, Danny and Baez are called to investigate the murder of a college professor who was involved with a scholarship program that has some questionable practices.

As the investigation unfolds, Danny and Baez uncover a web of deceit and corruption within the scholarship program. They discover that some of the students who received scholarships were not actually eligible, and that the professor had been taking kickbacks to look the other way. The investigation leads Danny and Baez to a suspect who they believe is responsible for the murder.

Meanwhile, Frank is soon to cross paths with his archenemy, Mayor Poole, as he tries to reconcile with the past. Poole was involved in a robbery decades ago, which Frank was investigating as a young cop. However, the case was never solved, and Frank has always believed that Poole was involved. When Poole approaches Frank, he tells him that he wants to clear his name, and Frank reluctantly agrees to help.

Throughout the episode, there are also several flashes back to Frank's younger years as a cop. We learn that he didn't always play by the rules, and had a tendency to take justice into his own hands. This causes Danny to question his father's integrity, and puts their relationship to the test.

In the end, Danny and Baez are able to solve the murder case and bring the suspect to justice. Eddie reaches out to her father and begins to mend their relationship. Frank confronts Mayor Poole and finally gets closure on the robbery case from years ago.

Overall, "Bad Blood" is another engaging episode of Blue Bloods, full of interesting storylines and character development. The flashbacks to Frank's past add a new layer to his character, and the investigation into the scholarship program keeps the audience guessing until the very end. The episode also explores the theme of family ties and the importance of forgiveness, making for an emotional and thought-provoking watch.
