Season 1 Ep.6. Breakfast time. Salene and Jack in the Café. Salene has a red line below the mouth. Jack's hardware on his glasses has mostly gone.
Jack retreats to the workshop to play with his radio, and eat a can of peaches from his secret stash. He hides the can when Salene comes in. She needs extra water to wash the baby. But note Salene's red line has gone, her eyes are blacker, and some of Jack's optical harware has come back.
Having been turned down by Jack, Salene tries Zandra. Lex unexpectedly offers Salene his own water ration. The red line is back, the eyes not so black. Jack has gone and come back to his workshop, and finds Lex and Ryan poking around in there. Jack's hardware is back to minimal as at breakfast.
