Yeah, but again mori only understand the meaning of mama, he calls everyone in the mansion mama, while rider has chose to be the papa, he even consider himself the dad in a married couple and miria the mom
When they learn what "papa" means and Mori starts to call Ryder "papa", only then will I call him "papa", too. Unless they make it a funny misunderstanding and Miria becomes "papa" and Ryder remains as "mama".
Cmiiw but ryder has never said he's the 'papa'. He in fact chose to be the 'mama' like everyone else in the mansion. He also didn't explicitly said he sees himself as a dad and miria as the mother. He only refers MIRIA as the mother/wife in their married relationship. It was never about a father mother relationship in the first place. Only a mama.
Even mori said ryder is his mama, so i wish people would stop calling ryder a papa
