Ash
Ash was a down-on-his-luck private detective. He had a pet cat named Dina. (source: http://matrix.wikia.com/wiki/Ash) Spoiler Having received an anonymous phone call, Ash traces Trinity and learns that other detectives have failed in the same task before him, one had committed suicide, one had gone missing, and one has gone insane. Eventually Ash finds Trinity after deducing that he should communicate using phrases and facts from Lewis Carroll's Alice's Adventures in Wonderland. It leads to a shootout between the Agents and Ash and Trinity. Ash gets wounded, and likely is killed being followed by the Agents.
