The chilling “Bones” season finale is almost here, and we’re officially worried for Brennan (Emily Deschanel).

The Puppeteer is possibly the most manipulative villain the team has faced to date, and he’s even more threatening when you factor in that he seems to have a strange fascination with Brennan.

After trying and failing to get rid of the terrifying nightmares that are plaguing her, Brennan can’t tell whether her paranoia about feeling watched is a product of sleep deprivation or if someone is genuinely stalking her every move.

We’re willing to bet that whoever this Puppeteer is, he’s keeping a close watch on Brennan these days and that’s why she’s been so on edge.

In Zap2it’s exclusive sneak peek, Brennan’s dad (Ryan O’Neal) seems to be thinking the same thing, since he urges her to be careful despite the fact that she’s got no evidence she’s even in danger. There are those stellar paternal instincts at work! Let’s just hope his piece of sound advice can keep Brennan out of this serial killer’s clutches.

“Bones” airs Thursdays at 8 p.m. ET/PT on FOX.
