When Clark discovers Lionel threatened to kill him unless Lana married Lex, he goes after Lionel to silence him once and for all. Lana tells Lex she is leaving him and Martian Manhunter makes a return appearance to help Clark stop Lex. The young Luthor is trying to find the last wraith from the Phantom Zone in order to use its DNA to power his army of super soldiers. Meanwhile, Lois goes to Reeves Dam in search of information about Lex's secret lab and is brutally stabbed by a security guard. Finally, Chloe's secret power is revealed; it is resurrection, or at least something like it. This was a very good episode and the Clark-Lana relationship has ended. Those two have been going around in circles ever since the beginning of the series. This episode featured solid writing, acting and directing.
