In an effort to protect the rest of the team, Oliver decides to register for the Vigilante Registration Act to see what the government plans to do with the new law. As he suspected, it was a trap to lure superheroes to an undisclosed location where he is confined to a jail and subjected to a battery of brutal tests under the supervision of Col. Slade (Michael Hogan). Aquaman (Alan Ritchson) and his new wife Mera (Elena Satine) team up with Clark to free Oliver. Lois is frustrated when Clark continues to push aside her offers to help the team and sets out to prove she can play with the big boys. Tom Welling directs.
