Charlie played bass guitar for the group Drive Shaft, but also played and wrote songs on the acoustic guitar. After Flight 815, he believed that he lost his guitar somewhere in the wreckage. At the same time, he battled heroin addiction. Locke confronted him about his drug problem, ("House of the Rising Sun"), and asked him if he would make a symbolic trade for the last of his drugs for the guitar. After Charlie handed his drugs over, Locke asked Charlie to "Look up", which Charlie believed Locke meant to pray. Locke told him to look up again, and when Charlie did, he found that his guitar was hanging off a tree branch, having fallen with a number of the other items in the cargo compartment, but was undamaged. The guitar was an Ovation, which featured a rounded plastic-backed shell.
