#9.18 - Upgrade

Metallo, Pt. II: Clark & Zod Forever <3

Thanks to Tess, John Corben is back and with a new upgrade: The Nice Guy Enhancer. Chloe tracks down Tess' lab for Clark, but little do they know that it's filled with red Kryptonite. Once Clark, or our favorite "Kal", is infected he falls in love with Zod because of his superpowers and takes him to the fortress to meet daddy. Meanwhile, Lois tries to get John out of the state and Chloe and Tess realize they are best friends/twins.

Brian Austin Green (Beverly Hills 90210) returns for his last special guest appearance as DC Comics original character John Corben, a.k.a. Metallo.
