Thursday's all-new episode of "Bones" will be very interesting as Booth and Brennan discover that they will be having another baby and Booth falls back into his old gambling addiction.

Although Brennan and Booth will be excited about the expectancy of their second child, the couple will also hit a rough patch in their marriage after Booth lies about his gambling habit in the next episode, which is titled "The Eye in the Sky."

"There's a big blowout about it," teased "Bones" star Emily Deschanel about Booth's gambling habit during an interview with TVLine.

"They don't know what their future is, if it's together or apart," she added.

According to Deschanel, Booth's relapse is triggered when he goes undercover to investigate the murder of a big-time poker player.

Executive producer Stephen Nathan also dropped spoilers about the rest of Season 10, telling TV Guide that they are not planning a grand introduction for Booth and Brennan's new baby.

"[The] baby won't be born this season," he said. "We figured we've been down that road, and I don't think we could have a better birth than we had for Christine."

In addition, viewers can look forward to seeing the Jeffersonian Team track down a murderer who evokes the memory of serial killer nemesis Pelant.

The EP went on to tease that fans should prepare for a not-so-happy ending in the Season 10 finale on June 4.

"We can leave the in a place that seems quite happy but is not necessarily free of tension and apprehension," Nathan says. "So it's not really a cliff-hanger, but there is a cliff."

According to CarterMatt, the synopsis for Thursday's episode reads as follows:

"A high-stakes gambler's remains are discovered in an industrial shredder, but Booth's history of addiction comes into play when he and Brennan investigate the world of underground poker. Meanwhile, Hodgins invents a lab-related product; and Brennan and Booth get some exciting family news."

"Bones" will return with Season 10, Episode 15, "The Eye in the Sky," on Thursday, April 23 at 8 p.m. ET on Fox.
