That's the thing. I assume that they have some cover story already re: covering up the Bat secret, so I don't understand why they'd sound so suspicious, all of them. Particularly Dick. Why's he darkly hinting at "hard knocks" after his parents death? What's the interviewer supposed to assume he means when he just claimed he didn't much even know Jason, the "hard knock" they're speaking about now? Why's he qualifying his life with Bruce--which to an outsider is very stable indeed--as just "as stable as any" and "not all fun and games?" That seems to suggest the worst of both words--as if his life was both decadent and dangerous.
And where he points out social workers wouldn't let him stay at the circus--I assume he's supposed to be accusing them of not really caring about him in general so why are they showing up now, but it risks coming across like he blames the authorities for taking him away from his "real" family still.
And then there's the whole "He wasn't my father and he never tried to be..." what's that about exactly? I assume it's like he's respecting Dick's parents and so never tried to literally replace them but it's a little off in this context. Is that supposed to make him sound like a good parent that he never tried to be a father to the small orphan boy? Wouldn't that imply he didn't try to be a father to the boy he adopted like a son? Originally I thought this was Devin Grayson and thought Dick just automatically correcting on that issue because it's a little sensitive for him (and this is pre-adoption for him) but what's it supposed to convey to the social worker? I think Dick would be able to convey these ideas in a lot less suspicious way that made it clear Bruce never expected him to forget his family but was still a father to him.
It sounds like he's trying to hint to the guy to check further and that seems completely OOC for Dick. Not just because he'd want the guy to leave but because afaik he doesn't view his time with Bruce this way, really. He even sounds off from Bruce, who's asking if he was a good father where Dick's saying he never tried (with him at least). Though that, at least, I could chalk up to misunderstanding between those two characters.
