Heartwarming / Barbie as the Princess and the Pauper

• When a curious King Dominick (still disguised as a servant) listens in on Erika (whom he thinks is the princess) singing for a moment, then walks back to the audience room with a lovestruck smile.
  • There's also the fact that he was there in the first place because he wanted to tell her the truth before anyone else—even the queen herself.
• Erika and Dominick's Falling-in-Love Montage to the song "If You Love Me For Me".
• "A Girl Like You." Erika and Anneliese immediately form a close friendship upon realizing how similar their situations are from a certain point of view, and sing a very sweet duet together.
• While they're stuck together in the mine, Anneliese uses a rock to show Julian how she feels about him by breaking it open to show the sparkling quartz inside to compare him to it: it's unassuming on the outside, but beautiful and valuable within.
• The novelization confirms what many fans already guessed: Erika gets out of debt because Anneliese pays it off at the end, freeing her best friend from what would've been a lifetime of indentured servitude. And then, Madame Carp goes out of business because the castle quits buying from her — presumably because Anneliese made it known to her mother how appallingly Erika was treated there. That's friendship.
• The fact that Anneliese's cat Serafina is Spoiled Sweet and genuinely likes Wolfie, dog-like eccentricities and all.
• Dominick went undercover as a page because he genuinely wanted to get to know the woman he would marry. Later, he trusts Erika's word enough to go undercover again and likely risk a diplomatic incident to break her out of jail.
• More of a tearjerker, but when Erika is revealed as an impostor by Preminger, Dominick is the person she turns to as she's dragged away. Of all the people in the room, including the queen (who has just been told that her daughter is dead), he is the one she most wants to convince that her intentions were sincere.
• Erika's obvious relief upon escaping the dungeon and seeing that Anneliese is alive.
• Despite being terrible at it, Anneliese makes a genuine effort to help out Erika's older coworker with the sewing when she's stuck at Madame Carp's. When the other woman, having realized that Anneliese is telling the truth about being the princess, says she doesn't have to do this, Anneliese simply responds, "I can't let you do all this by yourself!" The woman is clearly touched.
• Julian secretly steals the queen's spectacles when Erika steps in as Anneliese—even though the girls are identical (thanks to the blonde wig), he knows Anneliese's mother will be able to tell her daughter apart from an impostor if she's allowed to get a good enough look.
