Batman looked up from his screen. When Wonder Woman arrived on the Watchtower he was curious if she would come down to see him, or if he would be left to his own devices. While he was preoccupied by the possibility of Jason, he couldn't will the tests to be finished any faster.
He didn't mind her presence, Diana was one of the few people outside of his tight knit circle he trusted, and whose company he... enjoyed to a certain extent. Given that the last time they spoke outside of a crisis was when he was pretending to be Bruce Wayne, he was pleased with the chance to talk to her as himself.
