The Reds finally get their plans from Lopez, which prove to be less than helpful. Meanwhile, Church continues to be unimpressed with Doc's diagnosis.
This episode has examples of:
- Cliffhanger: O'Malley leaves Doc, Tucker has his baby, and a spaceship lands on Donut.
- Comically Missing the Point: When Doc realizes that Tucker is about to have his baby, he asks Caboose to boil some water. Caboose asks, "How can you think of soup at a time like this?"
- Death from Above: The episode- and season -ends with a spaceship suddenly dropping down on Donut out of the blue.
- Now You Tell Me: Andy reveals that Elites can infect people with parasitic embryo, which is likely how Tucker became "Pregnant". Church, outraged, demands why he wasn't told sooner.
- Unwitting Instigator of Doom: Red Team using their radios to contact Command gives O'Malley the opportunity to leave Doc. As the following season shows, this will have major repercussions.
