Revealing mistake: Gallant is watching over some duck eggs that are about to hatch. At the end of the episode, two of the ducklings have hatched and Gallant is showing them to Carter and Susan. An unhatched egg falls out of Gallant's bundle and smashes on the street.The smashed egg has a large yellow yolk and clear fluid, like an egg in a grocery store. But an egg that close to hatching would have almost no yolk remaining and an almost fully developed duckling inside.
Revealing mistake: As Carter walks into the baby's hospital room to see why it is "crashing." In the long shots the baby is obviously a doll, and its mouth is closed even though it is crying.
