Holy shit
It's so subtle, yet it explains so much.

Huh… Interesting.

I'd actually like to see something that shows Pink and the other Diamonds interacting that's actually sweet and wholesome. Maybe when White makes her way into the plot, we can get another flashback or two.

We already know Yellow and Blue cared about her (even if they had trouble showing it) but all we have for Pink is her getting suuuuuper pissy at Yellow and then planning to screw them over something fierce. Doesn't paint the best of pictures.
