First, that they neatly take care of Lance by killing him off with all his knowledge because nobody really wants Dick to have a brother, right? Especially one who's a rat? (If you've read BftC #2...Lance has got a ways to go to beat Jason there.) Don't ask me how that flimsy looking cape is actually protective.
Then there's the lingo--swinging, zing, and best of all dig. Dick digs Bruce.
Then there's Bruce's great testaments of love for everybody. Lance's dad is the best he ever knew. Except his dad who was the bestest best! And Dick means more to him than anything in life! And Bruce is just the greatest guy ever--just ask Dick! Awwww!
Also Dick getting in trouble for Lance's antics. Honestly, not since Opie Taylor has a kid's father been more willing to believe the worst of a kid with better character.
Also, Bruce's costume still seems to be in its plastic bag from the dry cleaners.
