Hope was a little girl who in the Matrix had the ability to change her RSI at will, sometimes adopting the body of an elderly woman or a grown man. She resided in Saint George's Orphanage and had a white rabbit stuffed doll.
Perhaps the Agents didn't want her to be found, and the orphanage was burnt. The next day, Eight Ball went to the deserted orphanage to find her but he was killed by fire, not listening to Charon's warnings. Soon after, Link made the attempt and realized that the tag was on a man instead. He followed him on the roof while chased by Agents.
Link saved her, by riding a phone line to the ground and eventually rescued her from the Matrix.
