Wait wut but why does his dad looks so young, is that an old photo?

For sure, remember his hair now? It wouldn’t just grow back like that

I think that was an old photo but thats also what he looks like now since i think it was mentioned that he didnt age he just looks old cause of all the hair

i think its due to the fact that time moves differently in the dungeon, the dad thought only some time had passed, but it was years, that was why he didnt age? i think i may be wrong tho, its in the chapter they discovered the dad
