Having him be aloof and mysterious was cool for the first few adventures, but for the amount of time that Aaron was traveling with Aph he should have been making SOME sort of relationship with her squad. This man was present since BEFORE Garroth was lost to the Irene Dimension. Yet all anyone had to say about him was "I didn't know much about him" "he was a good man". The group didn't even need to know him all that well, or be super close. He didn't need to expose all his secrets or be particularly socialable. But you're telling me that during the span of time that Aaron was around the same people, all the time, risking their lives...and he didn't interact with them on a more personal level? He ONLY interacts with Aphmau. That just isn't human nature.
I vaguely remember multiple characters getting shamed or dismissed for being concerned about his intentions. But looking back that is completely valid! From Aph's perspective, Aaron is a good guy who had proved himself, and doesn't need to explain himself ever. From everyone else's perspective, he is a complete stranger, with vague intentions and questionable goals, who they have know for at least a year in close proximity but goes out of his way (quite literally every single time) to interact with NO ONE but Aphmau.
Suspicious Behavior. That or he seems rude. But their distrust of that kind of put out is not unbased. Especially when his past comes to light, yet he is still no more than a stranger, and shown to be purposefully secretive. Suspicious Behavior. But the cast is supposed to ignore all that because...? "He's a good guy" how would anyone else know that?
I mean he doesn't have to open up to them in great lengths and cry about his tragic life, but by time he died he should have had a surface level relationship with the main gang. More than never knowing jack about him as a person. Training/mentoring with Laurence, amicable acknowledgement with Garroth, maybe teasing flusterable Katelyn. A joke or two outside of Aphmau. Just any amount of relationship outside of Aphmau. Please.
Otherwise his mysteriousness becomes an archetype instead of characterization. And it became more of a hindrance to the story, especially later on.
Having Aaron never build relationships with anyone BUT Aphmau sets him aside in a way that is very odd. Aaron is essentially NOT a character, but a plot point. He only exists to advance the plot, add suspense, or subvert the plot. But he himself had no character- other than grief.
And it especially took away from the significance of his DEATH! When he died the only person really grieving HIM was Aphmau. Everyone was sad for HER. It made so Aph could be sad but - "oh nobody else understands my grief". While Aph was grieving nobody could really grieve with her. It isolated her in a way so jarring and disconnected from the story it felt more like a plot diversion than a plot point. And everyone just continued with their respective plots, yet the STORY had to come to a screeching HALT after Aaron's death because aph was mouring and she is quite literally OUR EYES.
There in lies the problem. NOBODY could mourn for Aaron, because he was a stranger. But HE DIED! He died without ever getting to grow or build new relationships as his story was clearly building up to do. HE DIED with no mourners! What kind of depressing precedent is that?!? "You don't need to grow past your grief, and build new relationships after great lost! You just need to be HOT and (somehow impregnate) the main character! Plot 😃".
What a Lackluster death for a character!! A main character!!! To be mourned by no one. It should have been Aaron's death that brought the story to a halt, the fact that they had lost HIM. Not that Aphmau had lost him.
Aaron's death should have affected the entire cast, or at least the main one who had traveled with him so long! Yet everyone else is allow to move on as they would because essentially they lost nothing.
Yeah, we were all sad when Aaron died as kids. Because Aphmau was sad (that scream was something else). And, yes, Aaron's death was sad. But imagine how devastating it would be if EVERYBODY knew him- to some capacity- if everyone mourned his passing. Imagine how much more significance it would bring to his SACRIFICE.
Aaron was a man with nothing to lose from DAY ONE. BUT HE STAYED THAT WAY! He never grew! What kind of sacrifice is it for a man with nothing to live for, no mortal ties, to sacrifice his life.
It dumbs down his death to in essence, achieve his ONLY goal in life: revenge, and make his girlfriend-not-girlfriend happy.
He A STRANGER. Not because HE necessarily wanted Garroth back, but because Aphmau wanted Garroth back. It doesn't work well. Aaron should have sacrificed himself for Garroth because HE wanted to, because HE cared for Garroth.
It objectified him in a sense. His decisions- his world revolves around Aphmau, and only her? (And Zane strangely enough). He has free will but his choices like agency, desire, depth. He's a means to and end, hardly a character. He experienced no growth, no change, no discomfort.
He only experienced pain and Aphmau. Tragic.
