Act One

Act Two

Act Three

The next morning, in the NCIS elevator, everyone leaves to begin another day of work except for McGee who remains in the elevator with DiNozzo waving at him.

As Ziva arrives, DiNozzo remarks that he thought that being sent to the principal's office was bad.

"He's still in the elevator?", Ziva says.

"Per Gibbs's orders, awaiting El Jefe's arrival", DiNozzo replies, causing Ziva to whistle and wonder just how mad Gibbs is.

"Well, considering McGee's been covering for his sister who's implicated in the death of a Navy sailor..", DiNozzo begins, only to stop as the elevator opens with another worker leaving while Gibbs comes in, hitting the button while asking McGee what he was thinking.

"I say he's handling it pretty well", DiNozzo finishes.
