A revealing new promo for the upcoming tenth season of Fox's Bones has been released, featuring a steamy make-out session and a baby revelation.

Bones Season 10: Dead Man's Corpse Could Help Spring Booth From Jail

The new Season 10 trailer for Bones was released via TVLine Thursday, focusing on Booth (David Boreanaz) ready for some revenge after being thrown in jail. Brennan (Emily Deschanel) is speaking with Booth on the phone while the latter is in prison, before the call is interrupted.

"Are you sure you're okay?" Brennan asks him.

Booth replies that he is "mostly just bored," as a correctional officer ends the call just as Booth is telling Brennan he loves her.

Another scene shows Brennan during Visiting Hours at the jail, speaking with Booth about the conspiracy.

"They're counting on you getting killed in here, Booth," she says. "That way they keep their hands clean."

When Booth changes the subject to their daughter Christine, asking Brennan how she's doing, Brennan replies, "terrified, she'll never see you again."

After Booth gets out of jail, he and Brennan have a very intimate sex scene, in which Booth is shirtless and passionately making out with Brennan.

He later says that he is going to seek revenge on those who separated him and Brennan with the conspiracy case.

"Whoever did this to me and my wife, they're gonna pay," he says. "Then after that you can have my badge and my gun and you'll never see me again."

The other big revelation is a new baby on the way. Daisy (Carl Gallo) reveals in the trailer that she is pregnant with Sweets' (John Francis Daley) baby.

Watch it all unfold when Bones returns for Season 10 on Thursday, Sept. 25 at 8 p.m. on Fox.
