Smallville :

Lex has been clandestinely 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 Lex has captured including Titan.

After a corrupt Senator, Burke, threatens to expose the secret labs, Lex 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 and Martha takes a job in Washington DC.
