i'm not quite sure about that, i don't think it changes much because sunday claimed that most things aventurine has answered under harmony's curse were nothing but falsehood and thus was punished as a result (with the 17 hours system) and as we know, aventurine genuinely did think that ratio dislikes him per his conversation with the harmony image— don't forget too that churin really said "to fool others, you need to fool yourself too." so.... yeah i think it may do a little to change sunday's mind. that said, at the end of the quest, i think it's strongly hinted that sunday actually knew that ratiorine was collaborating (since he told gallagher, "why do you think i just let him ran free afterwards and create a big scene in the auditorium which i took the liberty of clearing it up?")
