You know, i got to ponder. Are the aves actual slaves at this point? Look i know i made this point in the past. But outside of sadia brother Smiting one when it insulted Sadia. Which could just be an older sibling protecting a younger. We really haven't seen any quetz treat an ave poorly. Take for example page 43, Roko is shaped shifted into an ave. As you know a big meeting is going on and thus everyone need to be at their position. Roko gets spotted and manages to Easily talks his way out of it.
Hell, just look at the context of that page. Roko is trying to find the queens chamber. Quetz ask what it is doing. Roko says hey i was told to go their by another quetz. Only for the quetz to not question him, Not get angry, To just tell them the other quetz was just messing with him. Almost as if they had Middle management issues where the quetz bicker over scheduling. So something like this isn't even out of the ordinary.
Meanwhile, the volcano dragons apparently rule threw intimidation and fear. A tactic someone like saida would never use. As she actually cares about the aves. Truly makes me ponder what the actual quetz view on the aves.
