Blue Bloods season 11 episode 5 is going to feature a story surrounding Henry Reagan (Len Cariou). The previous episode hinted that Frank Reagan's (Tom Selleck) father might have been hiding a secret from the family. After all, the title of this week's episode is "Spilling Secrets."

Blue Bloods season 11 episode 5 picks up what transpired in episode 4. It was revealed that Henry had been secretly sending money to someone. There's a question as to who this person is and their connection. When Frank learned about this, he confronted his father about why he's doing this.

Henry, however, told his son to back off. There is a potential tension brewing between the two, and it could lead to some dramatic family confrontation later on. Frank's father isn't open to providing information, leading the Reagans to question his actions.

Considering the episode title of Blue Bloods season 11 episode 5, some of Henry's "secrets" will be spilled. There is a possibility that he is trying to help someone, and this person doesn't want to be known -- that's they're keeping everything a secret between them.

There's also a chance that Henry is being blackmailed by someone. Perhaps, he wants to keep this a secret to protect the Reagans. But then, this could mean that the person who's likely blackmailing him has been taunting him for a long time already, given his retirement.

Another question in Blue Bloods season 11 episode 5 is what would Frank's children -- Danny (Donnie Wahlberg), Erin (Bridget Moynahan), and Jamie (Will Estes) -- feel about this. They could also play a part in convincing their grandfather to spill the secret he's been keeping from the family.

The upcoming episode is, perhaps, one of the biggest stories for Henry. This storyline could reveal other secrets that could challenge the family moving forward. It could either cause additional problems for them or could make their bond even stronger.

Beyond that, other plotlines will be explored, as well. There'll be some updates for other characters -- including Maria Baez (Marisa Ramirez). Even though she's not an official part of the Reagan family, she became one of the most important characters in further driving the story.

Meanwhile, no new episode of the police procedural aired last week on CBS. The series went on a week hiatus, with the Jan. 15 schedule repeating season 10 episode 17. But, there's no need for a long wait as Blue Bloods season 11 episode 5 is set to arrive on Friday, Jan 22, on CBS.
