S4, E14: Less than an hour before the vortex is to open, the Sliders are on the move, trying to avoid the Kromaggs they have encountered on this world. Taking refuge in a cave outside the demolished city, they see a woman, Christina, struggling along with an infant. When they help her back to the cave, she recognizes their names: while she was imprisoned here in a Kromagg breeding camp, she became friends with Wade Wells. Thrilled to find out that Wade is alive, Rembrandt wants to go rescue her, but Christina stops him: Wade was shipped out yesterday with all the others.
