Alden Gets Excessive Levels Of Hate For Some Reason I Dont Get It - Tumblr Posts
Alden's "no reason to worry" thing makes it seem like he has a tendency to ignore problems/act like they don't exist, but the truth is actually the opposite. When the Council dismisses his concerns about Project Moonlark, he goes behind their back and spends 12 years searching for Sophie. He's constantly working on assignments, showing up in the middle of the night smelling like wildfires, etc.
He takes problems incredibly seriously. He just tries to downplay them for the sake of others, while trying to handle them on his own.
(That's what happens when someone is raised as the sole child of one of the most influential families in the world. He thinks that he's supposed to be capable of dealing with every problem by himself. That's also why, when he mind breaks, he doesn't tell anyone about the guilt he's feeling until it's too late.)
