06E21 - Prototype

Lex has been secretly trying to turn Wes Keenan, a military man who supposedly died fighting in Afghanistan, into a "super soldier" by injecting him with DNA pulled from the various meteor freaks he has captured. After a crooked senator, Ed Burke, who has been financing the 'Project 33.1', threatens to expose Lex's secret labs, he dispatches Wes to kill the senator. But Lois witnesses the attack and inadvertently becomes the super soldier's next target. Meanwhile, Clark tries to convince Lana to leave Lex, but she refuses and Clark becomes more suspicious about Lionel's involvement with Lana's motivation. Following Senator Burke's murder, Martha is asked to be his replacement in Washington D.C. which means leaving Smallville (and Clark) behind.
