Revisiting an intense period in the lives of the Bishops and Olivia.

Superhero twins Zan and Jayna (guest stars DAVID GALLAGHER and ALLISON SCAGLIOTTI) show up in Metropolis to help The Blur fight crime, but end up botching several rescues – landing Clark (Tom Welling) in hot water with the District Attorney's office. Clark decides to come forward as the Blur to clear his name.

Erica, Ryan, Father Jack and Hobbes (recurring guest star CHARLES MESURE) learn Anna sent a shuttle filled with a deadly V tracker team to find them, and must figure out how to stop the shuttle from landing. Meanwhile, Anna gives Tyler his invitation to the Live Aboard Program, and Chad confronts Father Jack on what he knows about the Fifth Column.

After a violent attack on someone very close to Anna, she delivers a message that the V's don't feel safe and will be leaving. Anna also gives a list of possible Fifth Column members to Chad, hoping he'll investigate and help in finding them. Meanwhile, Erica and the team try to track down a scientist who may have created a weapon that the Visitors are afraid of.
