- The CW's Official Description: FEATURE FILM SUPERGIRL HELEN SLATER FLIES INTO SMALLVILLE AS LARA — Clark (Tom Welling) learns Kara (Laura Vandervoort) is in Washington searching for the crystal. Kara is captured after she breaks into the lab and sedated with a kryptonite-infused truth serum. The serum causes her to relive a prior trip to Earth when she followed Clark’s biological mother, Lara (gust star Helen Slater), to the Kent farm. Clark arrives in time to save her but, after searing the machine with heat vision, he also falls victim to the serum and sees what Kara sees: his mother.
I despise Lionel Luthor
So with Lara's DNA being in the crystal and Kara and Zod and all the others it looks like Clark is the almost not quite last son of Krypton.
PS Did anyone else notice the scene where Lex was shot by that agent. Then in the next scene he's talking to Clark, totally fine without so much as a scratch on his shirt let alone anything else?
