He couldn't remember the death of his parents well. Joe remembered feeling sad, but he didn't remember how they died. Kurt never told him whenever he asked. He said that it was better left if he didn't remember why or how. Joe didn't believe that, though. He deserved the right to know how his parents died, but he couldn't pry it out from his brother. It wouldn't be fair for him to let his brother relive those painful memories.
Maybe it was best if Joe didn't remember his parent's death. Some memories just weren't worth the pain to be remembered.
