"I haven't seen none jump." Howard shakes his head, but he doesn't want to give the illusion of safety. He may not give a shit about Joan and may actively hate Sherlock, but he cares about John - and possibly more importantly, John's forgiven him for the disaster last Arena. "But I read a book when I was a kid that said scientists think they could do six feet vertical."

He stands up, brushing imaginary dirt off his pants. He gives a little mock salute to John, then a nod at Joan. "Good seeing you, Dr. John." That he doesn't name Joan or Sherlock, especially Sherlock, speaks as loudly as words would have.
