I suppose we should be glad he didn't make a "Robin, the Goy Wonder" reference.
Always nice to see cute Robin breaking down Batman's stoicism (and that Dick never grew out of the ability to do so), though I would have thought Dick might have been a bit more respectful in the Synagogue, though I supppose wearing a yamulke might actually qualigy, in a coincidental sort of way.
And yes, Ivy, CAN be fun, but she's more fun when she's a little more subtle.
And Ivy might argue that THIS was the day Robin became a man....
