“Blindspot” Season 2, episode 9 will give Jane Doe (Jaimie Alexander) a chance to prove her loyalty to the FBI.

In “Why Let Cooler Pasture Deform,” Jane will tip the members of Kurt Weller’s (Sullivan Stapleton) team about Sandstorm’s plan to attack. However, Jane’s deed will be discovered by her brother, Roman (Luke Mitchell), who may not be that loyal to her after all.

The teaser for episode 9 opens with Nas Kamal (Archie Panjabi) informing the team that she’s been after Sandstorm for the past six years. “I dedicated the past six years to catching Sandstorm. After today, everything changes,” she says.

The next scene shows Jane and Roman walking together into an empty room. Roman then points a gun at Jane. Shepherd’s (Michelle Hurd) voice is heard in the voiceover saying, “It’s time to say goodbye.” However, it is certain that Jane wouldn’t be killed off in the episode. In the next scene, the lead character screams at the top of her lungs after a shot is fired. By the looks of it, either Roman or Shepherd will die in the fall finale episode of “Blindspot” Season 2.

Meanwhile, Kurt and Ali’s (Trieste Kelly Dunn) relationship will also be put to the test. In the clip, Kurt tells Zapata (Audrey Esparza) that Ali is involved in a car accident. Zapata worries that something might have happened to their baby, but Kurt tells her that he doesn't know the details yet. Despite his personal woes, Kurt will still be part of the mission to stop Sandstorm.

The teaser ends with a cryptic message that urges viewers to watch the last five minutes of the episode. “Why Let Cooler Pasture Deform” will feature a big shocker before “Blindspot” Season 2 goes on a short hiatus.

“Blindspot” Season 2, episode 9 will air on NBC on Nov. 17 at 8 p.m. ET.
