In Unexpected (2001), Phlox tells T'Pol "When in Fellibia, do as the Phellibias do" and T'Pol understood what he meant. This episode, occurring approximately three years later, Archer uses "When in Rome..." and T'Pol does not understand what he means.
The actor who plays Talas in parts of the fight scene is clearly a stunt double with much larger breasts than actor Molly Brink's. When Talas first emerges from her quarters, she is wearing a leotard top that completely covers her breasts, and there is no cleavage. During parts of the fight, her breasts are suddenly quite large and spill out of the top, creating deep cleavage. Later in the fight, her breasts are small again.
