Eddie (Vanessa Ray) is getting a new look for the October 25 episode of Blue Bloods.

Officer Janko (remember, she's using that name on the job) is going to be helping Erin (Bridget Moynahan) investigate a mysterious cult in "The Price You Pay," and the photos for the episode offer a look at her undercover and sneaking around. Is Teen Wolf's Gideon Emery the one playing the cult leader?

Elsewhere in the episode, Frank (Tom Selleck) seeks to vindicate Detective Douglas McKenzie (Mike Carlsen), accused of using excessive force, and Danny (Donnie Wahlberg) and Baez (Marisa Ramirez) search for the person responsible for killing a rapper's bodyguard. Plus, Jamie (Will Estes) is skeptical about a relationship between Espinoza (Luis Antonio Ramos) and a new rookie officer, Sarah Brooks (Lily Brown).
