[Barnaby's stare is stony even in response to J's playful tone, and when that arm moves to his shoulder to draw them together, he's rigid. His expression softens only a fraction when their temples touch, but he otherwise doesn't reciprocate. He doesn't shrug him off either, tolerating the gesture when it might be the last shred of affection he ever receives. He might be alight with anger, but it doesn't mean he's not immune to kindness where it's still offered.]

Because you're wasting your time on me. [Said as a dispassionate statement of fact. Unless he finds a way to both save as many people as he can and evade the combined might of the Kenoma and the Regent, he's going to be destroyed. By even showing him this much care, J is spending emotional energy on an investment that's worthless. A simple enough calculation, for one devoted to the destruction of countless lives for a higher purpose.]

You don't have to. In fact, it will be easier for you if you forget we ever spoke.

[Barnaby has only caused him problems, as happened in Venera. Continuing to associate with him now will surely only create more.]
