>>84087150Sui represents a very complex relation for Mori atm - they were once basically on par, but while the comet kept speeding past all barriers, Mori feels like she's mostly falling behind and their initial, colleague-like standing was just an illussion caused by Myth's special circumstances
it was a very heavily implied point of her talk about still wanting to do big things and reconnecting with other talents
tl;dr: the pedestal of success Mori places Suzy on also casts a shadow of doubt/failure on her own career, and the higher the pedestal grows, the bigger the shadow
