I don't know too much about the relationship between Dick and Wally, but unless I am mistaken, Tim and Conner eventually became best friends in the comics. Much like Bruce and Clark. It would be interesting to see if they incorporate that into this series as well. But seeing as how this Superboy already made a connection with the heroes that came before, it seems unlikely. More likely I bet we would see a Tim/Conner centric episode that in some way pays homage to that relationship. And if they do introduce Bart, even more so.
