Bones Bones

So much for "friendly" competition.

On Thursday's Bones (8/7, Fox), Dr. Brennan (Emily Deschanel) is asked to give the keynote speech at a forensic science convention, so she brings Cam (Tamara Taylor), Angela (Michaela Conlin) and Hodgins (TJ Thyne) along with her. But when the remains of a body are found at the convention, Brennan and her team must go to work — especially once Hodgins becomes the prime suspect!

). And as you can see in the exclusive first look below, there's no love lost between the two."Tess is a forensic novelist who has no comprehension of forensics," Brennan snips. But it seems Tess is trying to turn over a new leaf — and she even offers to make amends for her past dust-ups with Brennan.Will Dr. Brennan accept?
