they just don’t make characters like jon archivist sims. he spends an entire season having a forty episode long delusional breakdown and that’s only maybe the third or fourth worst period of time in his life. he gets intervened on twice. he gets kidnapped thrice. during one of those kidnappings he spends a month tied to a chair getting forcibly moisturized by a plastic ringmistress mannequin and no one notices. he fully dies for six months but gets up again when a friendly grim reaper gives his unbreathing body a pep talk. he spends several episodes at the start of the final season so depressed that it’s unclear if he even moves for multiple days in a row. the basis for his magic powers is that he is so traumatized that he begins to need continuous further trauma in order to live, which gives him the ability to explode people with his mind. he spends about fifty seconds at the top of an episode self-harming directly into a tape recorder, which is not even the most fucked up thing to happen to him that episode. he finally cried on audio for the first time in the penultimate ep and the only reaction I saw for several days after was wildly enthusiastic cheering. he’s missing two ribs and he’s at least 80% scar tissue by volume and the only canon information we have about his appearance is that he looks terrible at all times.
Sorry to bring this out of the tags, but it’s mentioned in episode 81: a guest for Mr. Spider
So on top of allthat OP mentioned, we can add the fact that this 30something year old already looks like an old man (:
