Smallville Ep. 11/1/07 - Lara

"Lara"

Kara goes to Washington in search of the crystal, but gets more than she bargained for when she is captured and injected with a kryptonite-infused truth serum.

The serum allows Kara to remember her previous journey to Earth when she followed Clark's biological mother (played by Helen Slater) to the Kent Farm.

Clark manages to save Kara, but winds up feeling the effects of the serum and relives Kara's journey - as well as his mother's!
