Tonight on Smallville…Blue
The CW official description:
HELEN SLATER RETURNS AS LARA-EL; CLARK MEETS HIS BIOLOGICAL MOTHER FOR THE FIRST TIME — Clark (Tom Welling) hears the voice of his biological mother, Lara (guest star Helen Slater), calling for help from Kara’s (Laura Vandervoort) crystal and decides to release her, despite Jor-El’s warnings. Lara and Clark reunite and she gives him Jor-El’s ring, which contains blue kryptonite. As Clark puts it on, he realizes Zor-El (guest star Christopher Heyerdahl) manipulated the whole thing and that blue kryptonite strips him of his powers, enabling Zor-El to take control of the Fortress of Solitude.

Kristin Kreuk, Aaron Ashmore and John Glover also star. Glen Winter directed the episode written by Todd Slavkin & Darren Swimmer.
