Sweetie Belle wasn't good. Her expressions were frowned quickly due to the actions she caused and had to hear from her sister. She felt ashamed as she thought that publishing Rarity's secrets on the newspaper was sure a bad idea..
She returns the boutique, where she opens the door and sees her sister. She was kneading a dress which was almost ready to wear. Sweetie thinks that Rarity was kneading it for her, and waiting for her.
Sweetie jolted in happiness, in relief and excitement the her sister forgives her now. She went forward to give her a big 'thank you' for the biggest gift.
But, she stopped when Rarity gets off her chair with the ready dress. Sweetie was curious about that, as she didn't knew where she taking the dress to? She finally founds it, which breaks her heart.
The dress was for somepony else.
She made the filly wear the dress, saying if it's size is good. The pony appreciates and hugs Rarity. This makes Sweetie break down into tears and runs away from the boutique by slamming the door from the inside.
Rarity hears the noise and sees Sweetie running away.
"Sweetie Belle!" The white coated unicorn cried.
Rarity soon cried shook her head as well in shame, feeling that she made Sweetie so upset.
"I'm so sorry, Sweetie.." Rarity said by shedding tears.
