From DC database: Synopsis for "Shadows of the Past"
Superman and Conduit continue to battle while Lois Lane secretly sets a trap for the villain. At S.T.A.R. Labs, Emil Hamilton analyzes the doppelganger body found in Superman's tomb. Superman finally catches Conduit off guard, using a sheet of lead to block the Kryptonite radiation in his suit, and then melting it onto his costume. A nearly powerless Conduit seemingly flees the fight, but is actually heading after Lois. When the villain arrives at her apartment, he finds her accompanied by his father. The nearly powerless Conduit is taken into custody once more when the Man of Steel arrives. At S.T.A.R. Labs, Superman is assured that a new specialist, Draper, will prevent any future escapes. While Professor Hamilton's tests have proven that the corpse that was found in Superman's tomb is actually the real Superman!
