In the interrogation room scene in Ocean's Twelve, a police officer is questioning Matsui when Isabel enters the scene. After some dialog Matsui breaks down crying.
What could Isabel possibly have whispered in his ear for him to break down crying?
The scene was meant to show that Isabel is a strong character and knows what she's doing. From the script,
They shrug. Isabel goes into the room with Evelyn. We STAY WITH Onderdonk and Davenpeck, who watch her through the two- way mirror. THROUGH THE MIRROR: Isabel walks right up to Evelyn, smiles, and whispers one word to him/her. Evelyn's face freezes. He/she looks at Isabel, scared. Then he/she starts to weep. Uncontrollably.... Tears stream down his/her face. Isabel hands Evelyn a sheet of paper and he/she begins to write. Onderdonk and Davenpeck are dumbfounded. Isabel turns around so she's facing them.
So, all that we know is that it was a single word, but we are never told what that word was.
