Adam gets Grady a job at Malloy's, and soon learns that Grady tracked him down because he was looking for Hardin...Hardin told the VietCong that his parents were CIA agents, which is how they ended up dead. Grady then disappears, and not only are Adam and Teddy looking for him, so is Hardin. Adam shows up at Chan's dojo and patches things up with Grady just in time for Hardin to show up. Grady's hopes of getting vengeance are squashed when (after managing to live through an explosing car), Hardin is run down by another car. (thetvdb.com)
