Sweetie Belle/Relationships

Skipper
Skipper tells Rarity he won't give the reason why they're denying the chimps maternity leave, suggesting he's not gonna say anything inappropriate with the Cutie Mark Crusaders in front of them.

Diamond Tiara
Diamond Tiara began bullying Sweetie Belle and Scootaloo after they stand up to her for making fun of Apple Bloom. She constantly torments the girls, and even forced them to keep telling lies about their friends.

In "Crusaders of the Lost Mark", Sweetie Belle helps Diamond Tiara find out what her cutie mark means and helps her re-mend her friendship with Silver Spoon. Diamond Tiara also stands up for them when her mother ridicules them.
