"Don't suppose you'll want to tell us where you've been and what you've been doing to end up so prematurely grey now, will you?" Alfred's plans for Master Bruce involved a lot of guilt, so he might as well know what he was going to be guilting him for ahead of time.
Dick, meanwhile, was having trouble calling people. Jason's message was, "If you're calling this phone, then you're family, and if you're family, then you know that I just got engaged and a clean bill of health. Cass' and my genitals are currently unavailable, but if you leave a message, they might call you back, which would be quite the trick." He probably wasn't going to answer.
