It's official: Eric Millegan won't just return to Bones.
He'll reprise his role as Zack on the show's 100th episode, scheduled to air on April 8.
As previously reported, the milestone installment will flashback to Booth and Brennan’s first assignment together. Says executive producer Stephen Nathan to Entertainment Weekly:
“We’ll see Zack during their first case and we’ll see the first meeting between Booth and Zack.”
Altogether now, Bones fans: Hooray!
