Looks like Dr. Brennan's separation from Booth is starting to wear on her on Bones.

In the exclusive first look at Thursday's episode (8/7c, Fox) below, the always no-nonsense Brennan (Emily Deschanel) is even more brusque than usual. When Hodgins (TJ Thyne) tries to offer some support about the whole situation with Booth (David Boreanaz), Brennan gets a little snippy.

"You've never been separated from your child, so that statement is false," Brennan snaps when Hodgins says he knows how hard the ordeal must be. "I appreciate your concern, but I'm fine - as is Christine and Booth, as far as I can glean. Is there anything you or anyone would like to know?"
