Remains discovered in the pinsetter at a bowling lane suggest foul play and require the reappearance of Wanda and Buck Moosejaw and the assistance of Bones' father Max who used to be in the victim's bowling team. Meanwhile, Angela works from the hospital via webcam as she comes closer to giving birth. The episode ends with Brennan telling Booth that she is pregnant and that he's the father of her unborn child.
Tropes
- Asshole Victim: The Victim of the Week was disliked by just about everyone else to the point where when the murderer is identified, most of the people present side with the murderer and ask Booth and Brennan if they can let him get away with it.
- Bowling for Ratings: Wanda and Buck Moosejaw resurface as Brennan and Booth go undercover at a bowling tournament to find out who murdered another competitor, whose mangled body was found in s bowling alley pin setting machine.
- Breather Episode: After the insanity of the previous episode (Broadsky killing Nigel-Murray before being captured himself), this episode is lighter with the Victim of the Week being an Asshole Victim who no one is mourning the loss of.
- Call-Back: The first time Angela goes into false labor in "The Hole in the Heart," Hodgins freaks out screaming "where the hell are my KEYS!?!?!?!" repeatedly. In this episode, when Angela really goes into labor, after insisting everything is under control, and calm, and as soon as he's off-screen, screams "where the hell are my KEYS!?!?"
- Dénouement Episode: The previous episode has Vincent Nigel-Murray killed by a Cold Sniper, and Booth and Brennan sleeping together. This episode has the birth of Angela and Hodgin's baby, Booth undercover in a mullet as a bowler, and the revelation that Bones is pregnant with Booth's child.
- Double-Meaning Title: Refers to the team changes in the bowling game, the change in the pin settings on the lane, and Brennan’s reveal that changed things for the whole series since she and Booth were now a couple.
- Enfant Terrible: Amber, a particularly brittle, obsessive, bratty little girl on Max's bowling league. You know something's up when Bones declares several times that her child will never be like that!
- Foreshadowing: Bones and Booth spend most of the episode at a bowling tournament and are saddled with a "horrible child" as Bones calls her. In between dealing with the girl, Bones states "you and I would never have a kid like that" several times. Guess what she announces at the end of the episode?
- Innocently Insensitive: Subverted. The guy who comments on Wanda that "pap must be a baker, cuz those are fine buns" while Max is right there obviously doesn't care that people think he's a sleazebag, but he doesn't know that Max is her father, so when Max objects to the comment he thinks he "wants a piece of that" for himself.
- Maternity Crisis: Angela goes into labor in the lab.
- Panicky Expectant Father: Hodgins spends most of the episode going “is it time?” in a panicky voice every time Angela comes to talk to him in the lab. When Angela’s water actually breaks, he’s slow to get that it happened and starts off calmly. But as soon as Angela yells at him to get the car, he runs off yelling “where the hell are my keys??”
- Person as Verb: Wendell tells Hodgins “I’m about to Brennanize you” before launching into science talk.
- Precision F-Strike: When Angela goes into labor:Hodgins: Where the hell are my KEYS??
- Screaming Birth: Angela.
- Season Finale: The show's sixth.
- Undercover as Lovers: Done for the fourth time in the series, with a twist: at the end of the episode, Brennan reveals that she's carrying Booth's baby (the previous episode had implied that they'd slept together), and they actually do become a couple thereafter.
- Wham Episode: The episode ends with Brennan telling Booth she's pregnant with his baby.
- Wham Line:Brennan: I'm pregnant. You're the father.
