'NCIS' Season 11 Episode 15 Spoilers: Team Investigates Faulty Bulletproof Vests

On the latest "NCIS," Bishop officially became a part of the team, but not before hitting a few bumps in the road. 

In "Monsters and Men," it becomes clear that Bishop (Emily Wickersham) is hiding information about the Parsa case from the team. It turns out that she doesn't want anyone knowing that she is an expert on the renowned terrorist. She says that her failure to tell Gibbs (Mark Harmon) about her knowledge of him was simply omitting information, not lying.

Gibbs is angry when he finds out, and puts her on the sidelines, believing she cannot be trusted with the case. He is also warned by one of her former superiors that she was taken off the Parsa case because of her tendency to be obsessive. 

Bishop is confused as to why she was taken off the case, and decides to ask Tony (Michael Weatherly) why Gibbs benched her. Tony tells Bishop that Gibbs believes in trust and full disclosure. 

Bishop wants to earn his trust back, so she confesses everything to him. She tells him about being previously taken off the case, as well as about the direct contact she had with Parsa. Gibbs then begins to understand why she is so invested in the case. He decides to put her back on the case so she can be finished with it for good. 

Once they were able to track down Parsa, a series of events leads to Bishop almost being killed after Parsa traps her in a room with him. But Gibbs is able to rescue Bishop by exposing Parsa's weakness: his family. 

Gibbs uses voice recordings of conversations Parsa had with his sister to fake a version of Parsa's sister's voice. They use it to convince him that she is telling him to surrender. 

Gibbs is then able to get a shot at Parsa, finally taking him down. 

At episode's end, Gibbs learns that he can trust Bishop, so he offers her a spot on the team as a probationary agent. 

On the next episode, "Bulletproof," the team investigates faulty bulletproof vests. 

The synopsis for the episode reads: "After uncovering faulty bulletproof vests in a truck filled with stolen U.S.M.C. merchandise, the NCIS team attempts to locate both the source and any vests that had been shipped to military personnel overseas." 

In other "NCIS" news, rumors of Cote de Pablo returning to the show still remain rumors. When Michael Weatherly was asked about the possibility of her return at the People's Choice Awards, he said, "We miss her every day... and I really hope she comes back."

While her return is questionable, something that has a better chance of occurring is a Tony-centric season 11 finale. Showrunner Gary Glasberg told TVLine, "I'd really like to focus on and come up with something for the season finale that has a strong Tony element to it - in fact, we're about to sit down and talk about that." 

"Bulletproof" airs Tuesday, Feb. 18 at 8 p.m. on CBS.
