It’s no secret that, in the 5/14 season finale of the Fox series BONES (The End In the Beginning), BONES (EMILY DESCHANEL) and BOOTH (DAVID BOREANAZ) finally hit the sheets. What is being kept secret, however, is the return of ZACK ADDY (ERIC MILLEGAN) a regular cast member exposed as a serial killer’s accomplice and written out at the end of Season Three. At least a couple of BONES fansites have spilled the beans about ZACK’S return. Now, the big question is whether he’s coming back for good or just passing through.
