S10, E6: Concerned about Lois's safety, Clark diverts her away from covering the Vigilante Registrations Act by suggesting she cover another story. After he comes clean with her, an angry Lois tells him that she can take care of herself – but when a flat tire strands their car in the middle of nowhere, their plans take a turn for the worse and Lois ends up in serious danger. Meanwhile, Tess searches for a cure for Alexander (guest star CONNOR STANHOPE), who is rapidly aging.
