The King and I - Page 08

"I found it always too sad, that only Twilight was touched by Sombra's diary. Cadance is the Princess of Love... how could she be that cold at the end?"

Sombra's diary? In which episode was that?
Did Cadence even know it existed?
If she did, then ... maybe she felt that Sombra wasn't loving anything but power when he wrote it.
Maybe she even felt like he was still that way afterwards, and didn't want to take any chance of getting close to him to have him maipulating her afterwards?
