According to the Latin Post, "FBI Agent Chavez will be hot on Trubel's trail in the next episode of NBC's "Grimm." Last week's season 4 premiere of "Grimm" picked up right where the season 3 finale left off: Nick lost his Grimm powers, Captain Sean Renard was left in critical condition after being shot by Weston Steward, Monroe and Rosalee's wedding reception came to ruins and Sgt. Wu began to catch on to the paranormal activity in Portland, reports Entertainment Weekly. In the upcoming episode, Agent Chavez, played by "Orange is the New Black" actress Elizabeth Rodriguez, will become suspicious of Nick and his relationship with Trubel, who beheaded Renard's shooter. In a sneak peek video clip from the episode, which is entitled "Octopus Head," Chavez is seen interrogating Nick and transitioning right in front of him. However, because he no longer has his Grimm power, he cannot see that the detective is a monster. Nick will also have to decide whether or not he should try to get his powers back, or if he prefers to live a normal life. Several actors will make a guest appearance in the episode, including Bitsie Tulloch, Silas Weir Mitchell, Reggie Lee, Bree Turner, Phillip Anthony Rodriguez and Brian Letscher."
