Can someone explain Kandy Who's endurance to me? WHY.

Ru herself was a punk kid back in the day, so she immediately recognized what Pearl was doing. However, Ru's big mistake was sending Trixie to BTM2. She should've never been in the bottom.

100% THIS. Most people are not getting that while the song is very upbeat the spirit of it is more aligned to what Pearl did on stage. That's why Ru saved her, she embodied the song.
