I think oscar is an illegitimate son of the King

Yup, probably like the ghost maiden’s son or smth

Yeah. No that I thought about it. That's probably it, they have the same light hair color right??

Yeah that’s what i was thinking. But if that’s the case then the second prince should’ve seen him while he was playing. I feel like oscar might’ve been isolated from his mother as well and worked as a servant in the castle....
