What did Kaname do up unto episode 62 of Bleach?

In episode 61 of Bleach, Captain Aizen was apprehended by Saji Komamura because he had apparently faked his own death. He betrayed everyone of squad 5 and all the captains and is now no longer a captain anymore. He deceived Momo and then when he apologized to her, he fooled her again with a "Goodbye" and threw his sword at her and nearly left her to die. Then he continued working for Gin Ichimaru. Now here comes the best part. He was talking to Ichigo Kurosaki all that time about Rukia until Saji Komamura who looks as a fox found him and shouted his name "Aizen" and then at the beginning of episode 62, Aizen claimed that he hadn't seen Saji Komamura's face in a while and is still standing and smiling. "AIZEN. How can you stand there and smile like that? IT WILL NOT BE FORGIVEN. NOR WILL YOU. KANAME!" What was going on with Kaname Tosen prior to that part or episode on Bleach?
