Parker will do as he asks, though it's not exactly what he wants. She's going to let go of the knife, but more by throwing it at his shoulder. She may be tired, but it's likely she's got decent aim. At least she's not aiming for anything major.

Parker doesn't care he's a troll. Sometimes, people look different to her (and sometimes she hears music that isn't there). No, all she sees is that he's trying to take the oranges she's all but rightfully stolen.
