Oliver (Justin Hartley) and Clark reluctantly decide to ask Tess (Cassidy Freeman) for help with Lois. Meanwhile, after Cat Grant (guest star Keri Lynn Pratt) witnesses Lois as Isis using her superpowers, she decides Lois is the Blur and sets out to prove it. James Marshall directed the episode written by Genevieve Sparling.
