Smallville Season 10 Episode 20 – Prophecy
Smallville S10x20 Prophecy
“Clark (Tom Welling) takes Lois (Erica Durance) to the Fortress to get Jor-El’s (Terrance 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 (Chris Gautheir) 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 (Laura Vandervoort), who is also on a mission to stop Darkseid.”
The last episode before the finale of Smallville!
