Star Trek: The Next Generation Season 7 Episode 10

Trivia: Juliana mentions a modesty subroutine to get Data to keep his clothes on. It was probably this program that overrode his passive resistance agenda in "The Most Toys."

Juliana beams down to the planet with Data in two-inch black-heeled boots, but when she materializes she's wearing flats.

Geordi says that Juliana has an aging program "just like Data," which contradicts several previous episodes when they've stated Data will never age and his appearance won't change.

Data with his perfect memory claims that no one has ever described his violin playing as "beautiful," but Picard described it as such in "The Ensigns of Command."

In Juliana's memory chip, Soong talks about how he felt about her leaving. So...how'd he record his reaction to her leaving into her chip after she left him?

It's been previously established in previous episodes that both Deanna and Geordi can detect someone who is an android, but neither of them detect Juliana's true nature.
