Is Zack ever returning to Bones?

The question is on the minds of numerous fans of this show. Fortunately, Michael Ausiello asked executive producer Hart Hanson for the answer:

"We definitely want to have him back," Hanson said. "But you risk picking that scab too much and people going, 'Aw, bring Zack back forever.'"

Bones + Booth = Humorous, intelligent sexual tension.

Hanson added that the current rotating intern experiment has an expiration date.

"We don't to do the Murphy Brown thing," Hanson said, dating himself and referring to that sitcom's weekly story line of giving its title character a new secretary. "But we're getting a lot of good stories out of these new people coming in and shaking things up in the lab."

Two more interns are on the way, meanwhile: a devout Muslim (played by Pej Vahdat) and someone that is hearing impaired (not yet cast).
