[Suddenly, he's crossing the distance between them in quick strides, grabbing Arthur's hand that's holding the sword in a vice-tight grip, raising it above his head so Arthur won't be able to swing it at him.]
It is, now. [The words might be cryptic, but what he says next should make it clear he's definitely not the same person who was here, before.] And what do I hope to gain? I've already gained it. All the pain you're feeling, from the wound, from everything I said, from seeing people be hurt... all that pain is gathered inside you. And now, you're going to give it to me.
[The nogitsune feeds on pain, after all, and like all animals, he's always hungry. So he lifts his free hand, pressing it against Arthur's cheek, black lines appearing there, flowing from Arthur to the nogitsune as he drains that pain. For Arthur, it'll feel like draining, too, in a similar way that a vampire drinking blood would drain energy from their prey. But at the same time, draining that pain will also make the wound hurt less.]
