Tell her.
If the "opportune moment" is what you're waiting for, it's right now.

Right now, those three little…what in the hell is she doing?

Well, don't let her! You'll be in big trouble. You know that.
You were supposed to tell her before you did this.
Clink.
Never mind. Don't tell her anything.
"Pirate."
