In Smallville: Prophecy, Clark (Tom Welling) takes Lois (Erica Durance) to the Fortress to get Jor-El's (voiced by Terence Stamp) blessing for their marriage. Jor-El bestows a unique wedding gift on the couple - he gives Lois Clark's super powers so she can see what it's like to be him for a day. Unfortunately, the Toyman (guest star Chris Gauthier) has returned to Metropolis, so Lois must go up against the notorious villain instead of Clark. Meanwhile, Oliver (Justin Hartley) searches for the Bow of Orion, which he believes will remove the Omega symbol from his skull, and runs into Kara (guest star Laura Vandervoort), who is also on a mission to stop Darkseid.
