"You claiming subtlety would strongly conflict with my belief that you're both self-aware and not inclined to lie."

"I don't want to provide context." He wants out. He's not actually refusing to give context, or participate. That is the better option. He just... does not want to engage in the process. That he is going to engage in. And is saying so.

Consider it an admission.

And, ironically, engagement.
