>>3235300Personally, Carl and Markus were more like husbands with an age gap to me. Markus sleeps in Carl's bed right next to him, speaks to him in a teasing, flirty manner and cares for him like a wife would if her husband had had a severe accident and couldn't walk anymore.
I'll never be able to see him as Carl's son, no matter the possible dialog options. So this is weird.
