She and the Angel were able to get on the ship before it took off from Lily Pad Base 3. The stress however caused her to go into labor and Gale had to help her give birth to her son Skip.
Tally contracted Krypton Oxide poisoning. Though she came close to death she was eventually cured by Nightingale and Vivek.
