Last week’s episode of Bones had us wondering what Booth (David Boreanaz) and Brennan (Emily Deschanel) did under the covers in his bed. (He just held her after the loss of Mr. Nigel-Murray, right?) Tonight’s season finale (Fox, 9 p.m. ET) sends them undercover in a bowling alley, and we know what they’re doing: posing as a couple to solve a murder. Watch them in action in our exclusive clip below. Previewing the season finale for EW, Deschanel poked fun at her look: ”I’m kinda like the missing member of Quiet Riot or Twisted Sister,” she laughed. “That’s the crazy thing about Bones: It’s like, ‘We’re gonna go undercover!’ and we’re the most conspicuous people in the bowling alley.” Mullet jokes aside, she also gave us a serious piece of advice for the show’s ‘shippers: “People need to watch to the very end of the episode because things are revealed and something changes their relationship forever,” she teased. Is tonight the night they finally become a couple, or are our minds just in the gutter?
We’ll be chatting with executive producer Stephen Nathan after the finale airs on the East Coast, so post your questions for him here by 10:15 p.m. ET. Come back at 1 a.m. ET to read the interview. UPDATE: Let’s keep the comments section spoiler-free, lucky Canadians who’ve already seen the episode. Spoilerphobes, we’d recommend NOT reading the comments on this post, just to be safe.
