"Here," L looked curiously to his side. There you were, your hand held out to him, with a little red whistle in the palm of your hand. L observed the whistle, coming to the quick conclusion that you intended for him to take it, and did so.
"What is this?" he asked. Clearly he knew what it was, but he was asking what it was for.
"It's a whistle," you hadn't picked up on that fact.
Light, who was observing the situation from the seat next to L, perked up, "Ryuzaki meant 'what is it for,' (Name)?"
"Oh. Well it's a rape whistle."
Light's eyes widened with shock as L's brows rose in confusion. Picking up on the fact that they were waiting for your explanation, you smirked.
"I don't want pervy Light coming onto you in your handcuffed state," you felt your smirk widen as Light sputtered out refusals. Before leaving the boys you added, "Plus, I'm the only one allowed to violate you, Ryuzaki~"
As you left you heard Light grumble, "I don't know what you see in her Ryuzaki."
"She keeps things interesting, Light."
