The music was loud once the door was opened, but shut it was muffled at least. Tim didn't notice he had a visitor at all, or if he did he made no facial recognition. He'd been trained by the best. When he was supposed to finish something without stopping he would, Batman always said give everything. And he did. Even when it was fighting invisible opponents. Only when the form stopped on a dime did Tim look up. There were beads of sweat gathering on his forehead he whipped away from his skin with his arm. He'd been in there for a while obviously, more than just the form. It was a hard one, but just it alone wouldn't have caused much exhaustion on Tim's part. Not after the typical training Bsts put him through on a nightly basis. He almost missed those training sessions, without someone to guide him it was hard to do. He was in no way an expert in martial arts but he was obviously more skilled than your average beginner.
"How did you..oh..yeah, the fiction thing." Tim winced at it as if it were something sour that he'd eaten and left a bad taste in his mouth, but after the moment passed he softened and even offered a lopsided smile. "Was the music to loud? Did I wake you?" He asked after trotting towards it to turn it off and glancing at the time. "I didn't expect anyone else would be awake at this hour." Trying to be pleasant. He was in a mood, but it wasn't Andrew's fault so he was going to try not to take it out on him.
"It helps me concentrate..using the tempo to time." He added carefully making small talk.
