It probably isn’t it that way at all but idk Duster always shook me as a depressed guy at the beginning of Mother 3, like having a father that verbally abuses him (and due the training he has a a limp leg) and sleeping all day in order to hang around town at night alone (making some of the townsfolk think bad of him). He doesn’t seem the type that shows it. Idk the first part of the game really made an impression to me. The fact that he makes a bond with the DCMC and Violet kinda shows how alone he felt sometimes. Tane Tane island is also a good proof of this.
