The dialogue options can sometimes serve as a look into AO MC’s mindset. Look at their dialogue options for when they first arrive at Redwake, two of the dialogue options when responding to why they’re in Redwake say “Uh, I dont know” and “I was told to come here”, which strongly aligns with what they say much later in the story where they said that they felt very lost after losing their memory.
Sometimes, the dialogue options reveal that this MC is quite… well, someone with hubris, lets just say. When a guard revealed that everyone now knows that they infiltrated Fort Talos, the only two dialogue options are literally taunts. “Try screaming for help then.” and “Sure, bring them all here, I can beat them on my own” (reminder that Morden legit told them they cannot defeat everyone on their own, lmao)
Even side quests hints at it when you look at dialogue options in Forest of Cerunno, the MC sounding weirdly confident about beating everyone there. It’s kinda a running theme actually, as early as Redwake where they fought the pirates after literally coming out of a near death escape, to offering to beat up the Frost Brigands.
The one time they didnt was actually at Shura’s fight, in which the objective was to escape lmao. Probs where it all started.
It makes sense though, given that the main story implied that all side quests, MC does them, as one part of the story requires you to visit a location only found through a side quest (the Ancient Hall). And a lot of the quests that exists are outright crazy (Like Maya’s Fortified Ship Sinking Quest)
It’s probs their biggest character flaw as well, and funnily enough, hubris is in fact, the fatal flaw of most greek heroes.
There’s also even subtler hints of their personality through actions instead like MC defying what Ren and Beringer told them to do, which was to escape and instead went looking for General Argos, which was probably out of spite. There’s also the part that MC literally straight up went to Ravenna Castello like Carina taunted them into doing (which again, hurbis). Its just very subtle, but they exist
