Many times. He helped Roy recover Lian from Cheshire in the first place (Action Comics Weekly) when she was barely a toddler. She lived at the Tower for months, and was even at the restaurant meeting where Roy, Wally, Dick, Donna and Garth decide to put together a new Titans team (the one with Damage, Argent, Starfire etc )in the Devin Grayson Titans run.
