Fans can look forward to two intense, all-new back-to-back episodes of "Bones" this Thursday.

In the first episode, "The Lost in the Found," Brennan and Booth will go on the hunt to solve a murder involving high school students and bullying.

In the second hour, which is titled "The Verdict in the Victims," Brennan and Booth will have 48 hours to prove that an inmate on death row is actually innocent.

Executive producer Steven Nathan also dropped spoilers about the two-hour finale, revealing that it was a challenging to write since the series has yet to be renewed.

"It was a bit of fancy footwork, because we had to write a finale that was both a season and series finale from which we could return," Nathan told TVLine.

When asked if it will end with a cliffhanger, he responded saying "I don't know if you could say it's a cliffhanger, but there's a cliff. There's an emotional cliff, and a big bad from the past resurfaces in a way that is surprising."

Series star Emily Deschanel also teased that "Pelant, in some way, comes back from beyond the grave."

According to CarterMatt, the synopsis for both episodes is below:

"When the remains of a private high school student are discovered in a ditch, Brennan and Booth surmise that bullying was a factor. When Brennan finds similarities between her own teen years and the victim's, it leads the team to question whether or not the girl's death was, in fact, a murder. Then, with only 48 hours left till execution of serial killer Alex Rockwell, whom Brennan and Booth helped convict, the Jeffersonian team must race against the clock to confirm Brennan's new suspicion that Rockwell may not have been responsible for those crimes."

"Bones" will air Episodes 17 and 18 of Season 10 -- "The Lost in the Found" and "The Verdict in the Victims" -- on Thursday, May 7 at 8 p.m. ET on Fox.
