Back in January, David Boreanaz (Booth) tweeted a behind the scenes photo of Booth and Brennan (Emily Deschanel) visiting a hair salon, and now we finally know which episode it was from!

Based on what we know about next week's Bones Season 7, Episode 9: “The Don’t in the Do,” it appears that this photo will make sense to fans in as little as one week's time.

According to the Episode 9 synopsis, a corpse found at a local landfill leads the team back to a hair salon where the victim used to work. Sounds like our favorite crimefighting duo is simply in the middle of an average day of investigating.

Come to think of it, the killer might even be in the room with them at that very moment. Creepy.
