At the time that Tousen's full, flashback story was revealed in the manga, back then the chapter felt confusing particularly with whom Tousen referenced as his friend's killer.
Good grief, the anime episode cleared away those misconceptions.
Generally speaking, it was a decent episode because the dialogue was rich at portraying Tousen's inherent but flaming hatred against S.S. for taking away his friend.
I felt more understanding and sympathetic towards Captain Komamura, because he learned from mistaking Tousens' feelings and came to realize that he was like Tousen's before meeting him.
