[Normally, Nathan would not contest things like this. He hates conflict. But Lazarus is not the only one dealing with accumulated stress lately and things that he would usually just take and internalize are instead setting him further on edge.]

I'm sorry. But you are exhausting yourself and it does you no favours for your health or your ability to adequately analyze things. Perhaps you are not in a state but I do not want you to put yourself into one.

[Part of him appreciates the concern. Honestly and truly. He's been accepting the comfort that has been offered in the aftermath of what he's been witnessing lately. He's needed it. But it's only gotten increasingly strong over the past several days. And frankly, it's starting to feel like walls closing in. "You will leave it to me, understand?"

[And that wall just pushes in again, after that. He wants to say something about it, but just sets his jaw. He gives no confirmation one way or the other. No clear acquiescence.]
