What was he supposed to say? Could he really call him?
He had to do it though, so he pushed the call button, placing the phone to his ear as he crossed the road to the nearest park, he was just going to walk around until he was done with this.
"Hallo? This is John," he said when he heard the phone clicking from the other side, holding in his breath in expectation. He had no idea what to say, he was probably not welcome any way.
"John Watson," he pointed out after a moment, still not sure if Jim would remember him.
