TIM brings John and Stephen back to the Lab and, with Kenny, is able to bring them back to life. Jedikiah turns against Rabowski and, in the struggle, the Time Key is damaged. Rabowski makes his way to where Carol, Peter and Ginge are imprisoned, and Jedikiah turns the air and heat off. John and Stephen wake up, have to sleep to regain their strength. Jedikiah restores life support, locks up Rabowski and takes Peter to repair the Time Key. But Peter booby-traps the Time Key, and releases Carol and Rabowski from their cages. Attempting to escape, Jedikiah and Rabowski fight, but are transported by the Time Key to the surface of Mercury. Peter then uses the Time Key to return everyone to their own time zones.
