Can the team trust an old friend?
About a decade back.
Nothing says nostalgia like making everyone think the intern is a serial killer.

Which he’s not.
Zack Addy is not stringing up dead bodies and feeding them porridge.
it’s possible for you to go have nightmares about something else now.
Two hours after her kidnapping, Brennan wakes to find her former protege watching her.
Is that why he’s mad at Booth?
Maybe if he weren’t being framed for murder, we’d have time to answer these questions.
It’s almost like they’ve got unresolved issues.
Cam tries to keep it stoic.
Hodgins plots revenge against his old friend.
Booth, in one of the sweetest moments of the hour, just pulls Brennan into a hug.
Brennan, just admit it: You’re fond of Zack, too.
He’s also got surveillance tapes that show Zack repeatedly leaving the psych ward.
The last time we saw Zack sneak out, Sweets walked him back.
Did he start escaping again after Sweets died?
I didn’t think this was possible, but SweetsandZack just got even more tragic.
He’s the reason Hodgins has feeling in his legs.
Was Zack trying to get caught, or does he just not know enough people?
NEXT: These are Zack’s confessions
Hodgins visits Zack to thank him, but Zack has bad news.
Hope is what I was trying to give you.
But my fear is all I have brought you is pain."
The difference is that this time, Zack is motivated by something beyond logic.
Look what Sweets did for him.
He doesn’t need a miracle;Boneshas never presumed that there’s only one way to be okay.
While Hodgins is losing hope, Zack might have found it.
His gesture reminds Booth that Zack just isn’t the murdering key in.
Aubrey balks: “You realize we’re talking about the person who kidnapped your wife here.”
Keep up, Aubrey.
Everyone on this team has at least one person they’d kidnap.
And Booth’s gut is never wrong.
He must not have wanted to upset Brennan any more than he had to.
He should have risked it.
As if on cue, behavioral analyst Karen Delfs knocks on Booth’s door.
The evidence all adds up to his guilt.
She doesn’t want him to be alone.
I still have questions about how every non-Sweets member of this team fell out of touch with Zack.
Karen interviewed him; so did Dr. Faulk, therapist to the Puppeteer’s latest victim.
Zack talks about it like he’s flattered, but they just wanted to use him.
Both Karen and Faulk also happen to wind up on Booth’s suspect list.
Karen only left Kansas City because her married boss kept hitting on her, so she hit him.
You escape the clutches of one creepy boss, and everyone thinks you’re a murderer.
To be fair, she was just kidnapped yesterday.
But that’s no reason for Brennan to stop living her life.
She and Wendell find another body, and nothing bad happens, because Brennan is a reasonable person.
After losing his brother on the operating table, Roshan adopted his dead twin’s personality.
Even to save his own life, he can’t push the plunger.
He doesn’t have it in him.
Now that he knows that, he’s ready to rejoin society.
Some things never change.
Is there a way to pat an episode of television on the shoulder?
