It broke me especially because the writers didn't pretend it didn't happen, only the characters did. Having Quentin's bisexuality go from one scene that could be interpreted as a joke or a one off to an actual conflict the character experienced of knowing he could have a loving relationship with Eliot, but that he didn't have the courage to seize outside of Filory was oof.
Honestly I don't think I've seen another show that handled struggles with vulnerability and emotions that well.
