"Who were you with?" Anakin asked when Obi-Wan returned to their room in the Temple covered in bruises. "Obi-Wan!" Obi-Wan simply sat and took off his boots and socks, before trudging to his room.
"Obi-Wan!" Anakin jumped up from where he had been sitting, and grabbed his former masters shoulder. "Please, talk to me!"
"I can't." Obi-Wan's voice was a whisper "Besides, I can handle it."
"I'm not so sure." Anakin's voice was slightly calmer now that Obi-Wan had replied. "Because every day this week, you've come home with bruises! If you won't talk to me, please find someone to talk to?"
"It's not that I don't want to tell you Anakin, it's that I can't." Obi-Wan repeated, looking at his long-time friend. "There's no one I trust more than you but-" He shook his head. "You're better off not knowing." The he gently pushed Anakin's hand off his shoulder, before entering his bedroom and shutting the door behind him.
"Master!" Anakin protested at the door, dispair clouding his voice. Once it became evident that Obi-Wan would not listen, he left their shared rooms and went to someone he knew would listen.
But before he got there he saw something on the news.
Not the news that every sentient in the galaxy would watch, it was on the not-technically legal channels.
It was about a new fighter in the Pits, and when Anakin enhanced the image, it looked like Obi-Wan.
But it couldn't be Obi-Wan, given that Anakin KNEW he was in their rooms, and would not be able to get to the fight within five minutes.
But Anakin, on the other hand, could.
So he took off.
