Booth will celebrate a 30-day milestone from his gambling addition while the Jeffersonian team investigates the murder of a biker gang member-turned-yoga instructor in the next new episode of "Bones."

Earlier this season, Brennan kicked Booth out of their home when she discovered that he was lying about his gambling addiction and had put their family in danger. In the penultimate episode of "Bones," which is titled "The Life in the Light," things will seem hopeful for the couple until Brennan finds out that Booth didn't invite her to celebrate his 30-days-sober milestone, reports CarterMatt.

In addition, the preview video hints that Brennan's friend and colleague, Angela, may decide to resign from her position on the Jeffersonian Team.

"Ten years ago, Angela just started this job in a temporary capacity and has periodically reevaluated her life," executive producer Stephen Nathan teased, according to TV Guide. "She's committed to the Jeffersonian, but mainly because of Brennan and Hodgins. Now, she really wants to look at ... where she and Hodgins are going next, and this is a real game-changer for everybody."

The promo video also teases that fans may finally learn Angela's real name.

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

"When the remains of an ex-con and biker gang member-turned-yoga instructor is found in the aftermath of a forest fire, the team must navigate both worlds from the victim's past to find the killer. Meanwhile, Booth continues working hard to beat his gambling addiction and regain Brennan's trust, and Angela and Hodgins make a big decision that will impact their future at the Jeffersonian."

"Bones" will air Episode 21 of Season 10, "The Life in the Light," on Thursday, June 4 at 8 p.m. ET on Fox.
