She was really moved by his selflessness and was deeply angered when she found out he was immediately kidnapped and nearly beaten to death by the son of a crime boss who is the the same man he tried to stop earlier. Oracle ( Barbara Gordon) was able to track down his whereabouts but she was too late as he was succumbing t his wounds. He finally tells her to stop and gives her a letter. His last letter to his wife and asks Cassandra to give it to her. He then passes on.

Cassandra grants his wishes and delivers the letter. She watches as she sees his wife react to the letter. Saddened and having no idea what he wrote Cassandra makes a determination to learn to read and write.
