He does feel a little jolt of nerves when Frank decisively sets his coffee down and leans in, but it's mostly a conditioned response. Reid is very aware of himself as prey in general, not necessarily for Frank Castle but for the multitude of bullies and violent offenders out there in the world. There's a reason he stays behind a desk as much as possible.

His nerves settle the second they get back to his comfort zone: talking. "I have no idea if they'll make a documentary," he says honestly. "A book is probably more likely. But I promise that nothing you tell me will be part of it. Studying something is different from generic public interest." Which he evidently has some distaste for. Reid is not a fan of glorifying crimes, or mental illness, and the two are often intricately linked.

"As for me asking-- that is, I can, if you're sure." Reid looks more tentative, sliding one finger around the rim of his mug over and over. "... We could just start from the beginning." Frank refusing to answer whether he wants to talk about it makes it seem like he does, in fact, want to talk about it, at least to Spencer.
