Yes, but we've still seen Dick reacting to the news.
Actually, I don't think we have, have we? We never saw Superman tell Dick, we just end RIP with Dick nonsensically assuming he's dead, and then Aftermath, which it isn't clear is after RIP or FC, and Battle for the Cowl which comes after Final Crisis where Dick seems to have finished his mourning.
It's been a major irritation about the whole thing. For instance, who actually told Dick Bruce was really dead, or delivered the body to him?
but he's still very clearly very part of Bruce's death, which is only appropriate.
It would be, but I'd argue we haven't. He's a side effect of Bruce's death, not a player in it (If that makes sense).
You'd never kill Batman and have his son find out and react offpanel.
Again, I'd say that's exactly what we DID get.
But if you like, we can use Barry and Wally instead. Imagine Wally's reaction to Barry's return is to see him and go "huh? They said you were dead. Eh, whatever, what were you saying about Grodd?"
These days, wouldn't surprise me for a moment, alas.
As for Genocide, SHE was created in the present, but I'd say the Diana-derived raw materials and the Ares who created her ARE from the future.
