The question was if the bat kids knew about the situation with Bruce. I mentioned some of this already I just think I might need to recap. Dick met him in disguise (I haven't bought the issue yet but I saw scans) because Alfred didn't apparently want to risk triggering Bruces' memory. In Red Hood/Arsenal #4 we learned that Alfred didn't even bother to tell Jason that Bruce was alive. Jason claimed he didn't believe Batman was dead although RHA #5 shows him realizing he misses Bruce and worries about the death rumors being true. Before leaving town Jason takes a friends' advise to visit the youth center he used to go to before Bruce took him in.
Hearing a voice Jason turns to find a rather unusual sight.
Look at him totally taken off guard by this. He literally has no idea what's going on with Bruce.
If you remember one of Bruce and Jasons' biggest problems was communication.
Yet Jasons' more open than usual because he was starting to think he lost Bruce for good. More than that he appreciates everything Bruce did for him even before they met.
He doesn't know what Bruce is doing or why. Jasons' just so happy that he's alive.
Do you see how much this meant to Jason? He's awkward afterwards but he was just so thrilled to see him. And this is what Alfreds' willfully denying all the Robins. Bruce is their dad yet their not even told that he's alive?! Or is it just Jason?! Either way WTF Alfred?!
