LOVE THIS SO MUCH. (With the exception of Bludhaven police working well with Nightwing. It's not Bludhaven if it's not a Crapsack City!)
God, Batman. Showing up unannounced in Nightwing's city and starting to investigate without telling him? Dude, bad form. Hahaha, Dick getting to drive the Batmobile. :D You tell him, Dick.
Batman throwing himself at the train like that: ...what? Bruce, what? Why did you do that, man? Did you want to check that Nightwing was going to be there for you anyway, or...? No, seriously, how come he took such a risk?
YES HE LOVES THE PUNS. HE DOES. You know that's a requirement to be Robin. INCREDIBLY LAME PUNS MAKE BATMAN HAPPY.
T-Rex story is another layer of happiness. The trophies being for Dick. Eeeee. Alfred needing to tell Bruce off for Bruce to get it (or at least accept it) and Bruce getting the dinosaur without telling Dick.
And then taking it to Dick's lair in Bludhaven, which is socute and also bad form again, Batman. For serious, how would he like it if someone broke into the Cave without telling him? (Oh right. If it's a somewhat Batfamily member, he'd make her Robin.)
