Spoiler alert: This update contains more spoilers on Castle Season 7. Read at your own risk if you have not watched the previous episodes or seen the Castle 7x8 promo video.

For those who have not watched Castle Season 7 lately: Castle (Nathan Fillion) and Beckett (Stana Katic) are now married and have gone on honeymoon in the West. The Castle 7x8 promo clip shows the couple talking about their new status at work, and all seems well - until "terrorist" is mentioned.

"I'm gonna take over the [Castle Facebook] page 9:30 EST, 6:30 PST just b4 #Castle," Huertas announced to fans on Twitter. "Let's talk about being a hostage!" The actor said in another tweet. The promo clip of Castle Season 7 Episode 8 shows Espo on board a subway with a man who has a kill switch.

Beckett comforts an extremely (and understandably) anxious Lanie (Tamala Jones) in another scene. It seems Castle Season 7 is getting real and gritty again in this week's new episode. Beckett is expected to do everything in her power to make sure Javi comes home alive.

"Castle and Beckett need to uncover a gunman's agenda after he takes hostages, including Esposito, on the subway," reads the Castle Season 7, Episode 8 synopsis on TV.com.

Castle 7x8 was written by David Amann and directed by Jeannot Szwarc. Amann penned the Season 7 opener, which carries the Castle mystery storyline. Some fans are eager to find out if there would be continuity clues coming up in this week's new episode.

According to an ABC release, the guest stars on Castle Season 7, Episode 8 are: Will Rothhaar as Jared Stone, Maya Stojan as Tory Ellis, Nathan Anderson as Brent Reeves, and Wendy Braun as Carol Jarvis.

This is the first crisis the NYPD has to face since Beckett and Castle got married. Their friend's life is on the line. Lanie and Seamus Dever's Kevin Ryan would be in deep agony over the hostage situation. Fans will watch the newlyweds Castle and Beckett deal with this, and the couple will show to NYPD that they really make a good team.
