In the next episode of "NCIS," Delilah's (Margo Harshman) water breaks and is rushed to the hospital as her husband Timothy (Sean Murray) races to the hospital to meet up with her.

The trailer for the upcoming installment titled "Ready or Not" was just released recently which showed Delilah being taken to the nearest hospital by Abby Sciuto (Pauley Perrette) because she is about to give birth to a new baby. Timothy hears the great news but is in the middle of a murder investigation. Leroy Jethro Gibbs (Mark Harmon) nonetheless allows him to leave the crime scene and see his wife at the medical center. He sprints immediately without a second thought and is at the hospital in no time. However, once there, a long-haired man holds up the waiting room and takes the people there hostage.

Timothy is taken aback by the situation because he needs to get to his wife who is in labor. "We need help," he shouts to the nurses. Soon, Gibbs arrives to help with the situation. "Let everyone else go," he says to the unstable criminal who has his gun pointed at the hostages. "The clock is ticking," the perpetrator says to Gibbs and Timothy in the volatile situation. It remains to be seen what the hold-upper wants in the hospital and if Timothy will be able to witness the birth of his newborn son.

In the last episode, the team managed to solve a tricky murder investigation. A witness named Amber Davis (Laura Regan) turned out to be the murderer of two men who apparently covered up the death of her daughter. She took revenge on them by sabotaging their electronic devices which contributed to their deaths.

"NCIS" season 15 episode 9 will hit the airwaves on Tuesday, Nov. 21 at 9 p.m. EST on CBS.
