(Open Spoilers) How do you think Ferdinand thought of Myne’s knowledge before ending of P2V2?

Imagine how Ferdinand would try to explain it to himself. After reading the series I thought he would probably think she could either be:

1: with her knowledge and Mana quantity and blue hair, some kind of spy/plant from Lanzenave or the Adalgisa villa or some other duchy and her family’s and possible mynes own memories somehow manipulated with magic. Or paid silence.

2:A spy sent from Veronica’s side and she is a secret love child from the Veronica faction and she is in collusion with the high bishop to get at him. In which case mynes whole nice but stupid personality is an act to get him to let his guard down. And this theory would be plausible because a supposed genius kid as smart as myne would definitely be able to put on a convincing act as well.

3:myne wasn’t making shit up with the gods and was actually given knowledge and power by them, in which case failing to protect her could get him in trouble with the gods.

4: she is a prank from the gods in revenge for him pissing off erwearman and never completing the gbook. Or could even be a goddess in disguise herself. Who knows, maybe he could’ve made the mestionorra connection already and though she was mestionorra in disguise.

5: a abandoned child from a power nobles love affair and mynes parents found her on the streets but this would explain her mana quantity but wouldn’t explain her knowlege

Of course there would be holes in each of these theories but just imagine how confusing is was for him to try and figure out what her deal was. Her mana quantity might have been explained away by her just being a rare case of a devouring child surviving lots of mana, but her knowledge in combination with her mana quantity definitely makes it seem like she’s somehow a spy.
