Random idea I got with Forest...:
What if he had a cane? What if he got a leg injury that made it so he needed a cane to walk to not feel as much pain? It would explain way better why he quit the royal guard (cuz fun fact, he was a royal guard).
The injury would also be a bit more mental health related as his mental health is what doesn't let him recover and heal. Meaning also that a lot of adrenaline probably make the pain go away and let him use his leg as normal temporarily, meaning he can still kick ass when needed like when fighting Frisk, he would just be in agonizing pain for probably a week after that....
I drew the cane too short.... Oops...
This is just an idea though and I don't know if I should make this canon or not. I still haven't shown anything canon to the story yet too, more than a little backstory, so I can come up with whatever I want and not worry about canon OwO
