Jodi Keenan was the wife of Wes Keenan and the main antagonist in the Season Six episode "Nemesis" in the WB/CW TV series Smallville.
She was portrayed by Emily Holmes.
Jodi was a former explosive ordnance specialist in the U.S. Army who had been discharged for unruly behavior. She met and fell in love with Wes Keenan who was also in the military as both were Green Berets and became her husband. Wes had supposedly died in a helicopter crash, but she refused to believe it.
Jodi discovered LuthorCorp documents containing a file on her husband, leading her to believe that Wes was alive and was being held by LuthorCorp. In a series of underground tunnels, Jodi confronted Lex and Lionel Luthor in the tunnels underneath Reeves Dam. Lex asked who she was and the person took off her mask.
She says she only wanted Lex and set off a small explosion that blocked the tunnel, throwing Lionel several feet and covering him with debris. She knocked Lex out and drags him away deeper into the tunnel. Lex regained consciousness and the woman introduced herself as Jodi Keenan. Claiming Lex kidnapped her missing husband, Jodi threatened to blow up an underground maze with Lex inside unless he tells her where her husband is.
She had planted multiple charges throughout the tunnels and set them to go off within a matter of minutes. She told Lex that unless he lets her talk to Wes, she will blow the entire cave system up in 20 minutes and started a timer demanding that Lex call Wes. Lex finally admitted that Wes was dead; he had multiple injuries from which LuthorCorp tried to save him, but he died.
For a moment, Jodi lowered the gun she had on Lex unnerved. Lex then tried to wrest the gun from her and it went off, injuring Jodi's leg. Lex told her they could still get out of the cave alive, but she stated that the bomb was pre-programmed and couldn't be stopped. Just before she succumbs to her injury, she sets off another smaller explosion inside the chamber, enough to kill herself and leave Lex trapped with no hope of escape until Clark Kent eventually arrived and rescued him.
