theyre obviously drawing parallels of the wittebane brothers with hunter and luz, but hopefully with less fratricide. so what if it actually gets acknowledged in canon?

when they run into him, belos sees the echo of his brother with a younger human peer. they’re taking care of each other and gallivanting around in masks, having adventures like phillip and caleb used to. before they got to the demon realm and everything fell apart. before caleb fell in with the witches and phillip took the CLEARLY righteous path and rejected that world.

except luz and hunter have already been in the demon realm. luz has taken the magic and the culture of the isles and flourished. despite all of belos’s efforts, hunter has also studied wild magic and even ultimately betrayed him like caleb did. and now instead of convincing hunter to return to puritan sensibilities in the human world like belos wanted to do for caleb long ago, luz has converted them both to heretics. and their relationship is better for it.

but belos will never admit that the problem was himself. that if he had embraced the boiling isles, or even just tolerated his brother’s embrace of it, then he wouldn’t have “had” to kill caleb. so instead he looks on with envy at luz and hunter, who could have been phillip and caleb in another life but achieved this while doing everything wrong, and rages.
