'Blue Bloods' Season 7 Episode 5 spoilers: Erin gets out of her comfort zone, lends a hand to a familiar foe in ‘For the Community’

Everyone’s favourite family of cops is back this week as they face huge decisions on Friday’s episode of “Blue Bloods.” The fifth installment of Season 7, titled “For the Community,” centres on Erin (Bridget Moynahan) as she deals with a fight for justice that has morphed into a fight for one’s life.

“Devious Maids” actress Judy Reyes has signed up as a guest star on episode 5 of the popular police drama as Coryna Garza, a fierce and rambunctious activist who has stirred trouble quite a few times. She joins other “Blue Bloods” cast members, including Frank (Tom Selleck), Danny (Donnie Wahlberg), Jamie (Will Estes), Henry (Len Cariou), Linda (Amy Carlson), Nicky (Sami Gayle), Det. Maria Baez (Marisa Ramirez) and Officer Eddie Janko (Vanessa Ray).

According to TV Guide, Friday’s episode features Frank, who mulls over helping the U.S. Marshals as they gear up to raid a local gang. Meanwhile, Erin and Anthony give a hand to a leading community activist who faces deportation because she isn't a U.S. citizen.

CBS has posted a sneak peek of the Oct. 21 episode of “Blue Bloods” on its official site. In the trailer, Erin berates an activist for inciting the destruction of a private property and for punching the owner on the face. Later, Erin informs Coryna that Homeland Security believes her stay in the country is illegal. Frank advises Erin, “If you want to show the community you’re with them, you have to be upfront with this.”

In another preview video, Anthony starts to tell Erin about Coryna’s latest issue. Erin cuts him off, saying that she’s all too familiar with Coryna and that what the latter is doing is not community activism, it’s a crime. Erin says Coryna has crossed the line – there’s no denying that the activist has committed vandalism. Anthony tells Erin that she doesn’t have to deal with Coryna anymore – it seems the Department of Homeland Security has a reason to believe that she’s staying in the US illegally and they’re determined to deport her.

“For the Community” is directed by Peter Wener and written by Blair Singer. SpoilerTV named other actors and actresses who will be seen in "Blue Bloods" Season 7 episode 5, such as recurring “Blue Bloods” cast members Abigail Hawk (Det. Abigail Baker), Vanessa Ray (Officer Edit “Eddie” Janko), Robert Clohessy (Lt. Sid Gormley), Steven R. Schirripa (Anthony Abetemarco) and Esai Morales (Trey Delgado).
