Jor-El has no intent of catching anyone by surprise, and when he sees Damian, he approaches from the front, walking down the path that cuts through the park. It was a winding route that started at the science division's building in Metal, and would eventually reach his suite in Earth. Even with the capacity to fly (something learned with a level of doubt and difficulty- gravity was something hard to so easily dismiss), he prefers to have his feet solidly on the ground.

"Hello, Damian," he says as he approaches, from several feet away. It is enough of a distance to give the boy time to put everything away if he chooses. Whatever Damian is working on, it may be private, which is reason enough to give him the opportunity.
