Ash catches a Treecko.
Ash refers to his Treecko as male when, after watching it shove the oldest Treecko to the ground, he states "That's weird; looks like he's not good buddies with the other Treecko."
The title of this episode is based on the phrase "two's company, three's a crowd." It could also be based on a television show of the same name.
This is the first episode of the Advanced Generation series to have a boss fantasy, a segment that became prevalent for the rest of this series.
Although May claimed that Treecko are "creepy" six episodes earlier in Professor Birch's laboratory, she states in this episode that they are "cute".
