- Adam usually experiences melancholy over being the only human, but when another human arrives, he freaks out and experiences jealousy. This is an interesting point of character development for him, helping him realize how much he loves his obscure role at CDMS.
- A running gag in this episode, involves people assuming that either Adam's hair is constructed of fire or his head has caught on fire.
- Carla Farulo from "The Notorious Windsor Gorilla" makes a second appearance.
- Adam talks about his family. He mentions his father, being a penny-pinching individual and makes a first mention of his comical uncle, whom he calls "Uncle Marty".
- Adam says he should ask his stylist to give him a less "flaming" color of red. This implies his hair is dyed, supporting a claim by Jake in "Glazed and Confused", saying he's not a natural redhead.
- Adam can roll his tongue.
- Adam's scholarship at an animal school, has overtime, given him a fan club, among the humans from other human schools.
- The Possum Girl's name is never revealed. She is referred to as "PG" by her friends, as the initials for "Possum Girl".
