Well, looks like I was right. Completely forgot about this one…

Parece que a Tiara de Diamantes le gusta como canta Sweetie Belle.

Which is especially infuriating for DT because her special talent is being in control
 
In my headcanon she got her cutie mark in a semi-lucid dream, she could control it, but was unaware it was a dream because she has depression

@Graveheart  
Check out “Family Appreciation Day” at 6:58 – Silver Spoon, Sweetie Belle, and Diamond Tiara leaving the schoolhouse in that order, looking pretty happy with each other (apart from Diamond Tiara being in the midst of an evil scheme).
 
I suspect that Sweetie Belle gets along relatively well with Diamond Tiara and Silver Spoon outside of the DT&SS vs. CMC dynamic; even within that dynamic, DT&SS are least nasty to the CMCs when Sweetie Belle’s leading. Diamond Tiara mainly hates Apple Bloom, since Apple Bloom is a better leader and a better pony than Diamond Tiara, and they both know it…

@Wiimeiser  
Yep, that’s what I was referring to. :)

@Graveheart  
Ms. Strand herself confirmed she’s getting at least another side to her personality…

Future episode, per chance? The Diamond Tiara character development episode, maybe?
 
…Nah, just cute. <3
