The clip explaining about river from Serenity (2005) with Nathan Fillion, Alan Tudyk
May I see her?
I believe you've got some storytelling to do.
What in the hell happened back there?
Start with the part where Jayne gets knocked out by a 90-pound girl.
'Cause I don't think that's ever getting old.
Do we know if anyone was killed? It's likely.
I know she meant to kill me before the Doc put her out.
Which, how exactly does that work anyhow?
It's a safe word.
The people who helped me break River out...
had intel that River and the other subjects were being...
embedded with behavioral conditioning.
They taught me a safe word...
in case something happened. Not sure I get it.
It's a phrase that makes her fall asleep.
If I speak the words... Don't say it!
It only works on her, Jayne.
Well, now I know that.
"In case something happened. "
You feel to elaborate on what that something might be?
They never said what... And you never did ask.
Get your hands off...
Eight months. Eight months, you had her on my boat...
knowing full well she could go monkeyshit...
at the wrong word. You never said a thing.
I brought her out here so they couldn't get to her.
I don't even know what they... My ship!
You had a gorramn time bomb living with us!
Who we gonna find in there when she wakes up?
