In BftC, though, it makes sense for the Dick reaction Daniel set up that Nightwing wouldn't want to talk; he's supposed to be closed off and distant and stuff, so... Actually, I could imagine Dick not wanting to talk about Bruce's death anyway, either because of the secret identity issue either because he might be in denial.
There's a couple of comics where Jim's uncertainty regarding the Robin issue is explored, too. It's always nice to realize that there's less fucked-up of an authority/moral figure in Gotham than Alfred - who, you know, may not be Bruce-level of weird but was still pimping Tim as the new Robin.
I've read a couple of fantastic fics which explored the connection between Jim and Cass, too, and that was lovely. It's a shame that it wasn't used in canon, because there's a lot of potential there; saving him was her Establishing Character Moment, why wouldn't they have a connection?
