Clark begins to suspect that Davis is alive. When the police issue a warrant out for Davis' arrest, Chloe thinks it's best if they both left.  When Clark tells Chloe he has a crystal that could send Davis to the Phantom Zone, Chloe lies and says she thinks he's in Alaska.  Clark finds Davis in the process of killing Oliver, but takes Davis back to the fortress where he's about to use the crystal when Chloe arrives and stops him.
