Smallville - Season 10 Episode 8

Clark accompanies Tess, who got childhood nightmares triggered by a mysteriously delivered music-box, to the orphanage where she was left behind by her parents. They find out the hard way 'Granny', who runs it, far from her philanthropic image, in fact ruthlessly rules a brain-washed power girls ring. The general finally sent Lois the video made by her late mother when dying from cancer. Dealing with painful and sweet memories, she ends up digging in Clark's Kryptonian parental antecedents in the fortress.
