Fox’s “Bones” stressed on the importance of following one’s dreams in the recently aired Season 12 episode. Now, only two episodes are left before the crime series wraps up its final season. What will happen in the penultimate episode?

In short: A lot. The official logline of the episode has an ominous tone. It states that each leading character’s final story will begin to unfold. “Brennan testifies for Zack in trial,” it reads, “Angela reveals some big news, while Aubrey and Jessica come to terms about their future together.”

However, things will get heated between Booth (David Boreanaz) and the man who wants to kill everyone he loves as revenge for assassinating his father in front of him. Mark Kovac (Gerard Celasco) will rear his ugly head after he escapes custody in the upcoming episode, titled “The Day in the Life.” He was arrested in “The Scare in the Score.”

Once the Jeffersonian learns that Kovac escaped, it will be a race against the clock. Booth must find a way to protect his loved ones including his wife Brennan (Emily Deschanel). It soon becomes clear that he has a dangerous plan in store for Booth’s loved ones.

The preview of episode 11 shows a bomb exploding inside the lab. Unfortunately, the video hints that all of the Jeffersonian team members will be trapped in the lab moments before the explosion. Will a beloved character of “Bones” meet his/her end? We certainly hope not!

Moreover, a number of guest-stars will be seen in this episode. Cyndi Lauper reprises her role as Avalon Harmonia, Eric Millegan returns to the Fox show as Zack, Pej Vahdat returns as Arastoo and Raney Branch appears as Cam’s (Tamara Taylor) younger sister Felicia.

Catch the penultimate episode of “Bones” on Tuesday, March 21 at 9 p.m. EST on Fox.
