NCIS 〜ネイビー犯罪捜査班 Exclusive: What is "Rule 51"? 

"It’s a very, very poignant moment, pertinent to the rules, that will tug at the heartstrings."

The composing of rule 51 is a climax to the season finale, but not the climax. “If they think that’s the surprise, it’s not," Brennan says. "Anyone who watches the show gets it—they know they have to watch the last 30 seconds of the last episode of the season.” The cliffhanger this year is "not violent. But the anticipation of violence, and grief, and hurt, it’s astonishing. I mean, the audience will go, 'Oh my God, they’re not going to do that.' The last 20, maybe 30 seconds of season 7 will have people talking all over the summer. And it’s very personal."

You won't believe how nervous and excited I am right now.

Yay. Nonviolent! But what do they mean by "anticipation of violence . . ." Eeks!
