Eugene has been struggling with a robot he's making, and when a baby is dropped off at White's End, he is determined to study him.
This episode contains examples of the following tropes:
- Blatant Lies: At the end of the episode, Eugene says some clothes he sent to the baby's parents were "just something off the rack", but the photo reveals that it's a miniature version of Eugene's outfit.
- Bluff the Imposter: Eugene, suspicious of the police officers the doctor brought with him, casually mentions a fictitious policemens' benefit that evening. They agree, telling Eugene that they're imposters.
- Brainy Baby: The episode involves Eugene finding a genius baby and wanting to study him for an A.I. he had been building. It turns out that the Big Bad also wants to study him.
- The Diaper Change: Eugene freaks out when he realizes the baby he's watching needs a diaper change and finally caves to Dylan's constant questions as to whether he should "go get Connie."
- Evil Counterpart: The villain of the episode is essentially a version of Eugene without his morality. Both of them are "men of science" and initially want to study the baby (who happens to be a genius) to make advances in their scientific projects. But Eugene ultimately realizes that it's more important that the baby be safe and happy than that he finishes his robot, while the villain never gets this.
- Good Is Old-Fashioned: During the confrontation, he Big Bad calls Eugene's morals "outdated" — because kidnapping a baby to experiment on him For Science! is so advanced.
- Papa Wolf: Eugene becomes protective of his charge and ends up fighting to protect him from an unscrupulous scientist.
- Tempting Fate: Eugene responds to Connie's warnings that he'd better take his responsibility to the infant he found on the doorstep seriously with "What could be the least bit hard about babysitting?"...and soon he has to deal with the baby crying, spattering him with food, and other things he is not expecting.
- Unflinching Walk: After Eugene's robot PLATO is unleashed on the bad guys, he walks away, paying no attention to the maze collapsing behind him.
