Theory: Belos makes no sense and many others.
1 Some of Philip's dialogues have nothing to do with the character he is speaking with so he speaks to who knows what.
2 Hunter till now was an UNFINISHED grimwalker and it was his growing of-age story we got now where he stood up against his abuser.
3 Hunter and all the other unfinished Grimwalkers are made so because Philip makes them younger than their ortet in hopes they will not develop the same.
4 We still have no idea what really happened between Philip and Caleb.
5 The story about the brothers is a red Hearing.
6 Orphaned brothers don't have to be blood-related.
7 Caleb was not a good big brother (Personal opinion)
8 Belos might be seeing ghosts.
"This is for the good of your souls, you'll thank me later."
Whos souls is he even talking about at this point? It for sure is not Luz because he doesn't seem to care of her, he surely doesn't care of the other Witch children, he doesn't know Camilla and Hunter to him seems to be Caleb.
He called someone Evelynn? (I know it is implied to be Caleb's wife.)
But in here he makes no sense calling her out.
Philip wanted to leave the demon realm now he is going back.
This new special gave us NOTHING about him that we didn't already know, which to me means...they are missing a detail that will shift the entire POV.
When the story about the brother was told the last thing they said was. "Sounds like big bro got a hot witch girlfriend, and little bro got upset."
Why would you mock such an important plotline like this?
THAT if it is mocking but what if it is in fact a red herring? And once we get a single missing detail all will be in a whole new context so the creators couldn't have said it now because after hearing that all would have ended.
I mentioned in the past almost everything Philip says makes no sense in context with the others, even in this episode he called Hunter Caleb and no one bet an eye to correct him not even Luz called it out." HE IS HUNTER." Or something similar to this.
He even thanked Luz for getting a chance to make things right with this Grimwalker which he considered a failure.
So here are my crazy theories.
Hunter is an unfinished grimwalker and this was his coming of age.
In the book it's shown that Philip wanted a child version, I think a finished grimwalker is supposed to have its own eye color not pink, the pink eyes are a grimwalker that is still in process of being finished.
Because here Philip didn't make their eyes pink. So Philip was recreating a younger version of Caleb.
Caleb died when they had his fight and he "betrayed" Philip. So Philip made a Grimwalker that was younger than Caleb before he got to betray him... which means now Hunter is the age Caleb was when he got killed probably or around it.
Now I have to say this might sound crazy but ... or Philip went insane in the last episode and talks puritan nonsense OR he actually sees souls/ghosts to some capacity. We have seen that Palismans have souls, we have seen Eda and Luz and King switch bodies so a concept of the soul exists, and we have seen the forests in Willow's mind same in Philip's mind so souls are real.
I believe Philip creates a grimwalker that is unfinished because it's not the proper age their ortet was in the hopes it will change the outcome of the decision their brother made, and if it's a perfect outcome it can be fit for his brother.
Philip should have died in this special but he didn't why ? Because we don't have his full story yet, we barely have any real story from HIM. All we know was told to us from others not him.
But even so he has so many mysteries yet it's impossible to look away because everytime he speaks with someone he is 1 manipulating them or 2 making no sense but the character try to make sense out of what he speaks.... so at this point I can even believe he literally sees the ghost of his brother.
Even so, Caleb was NOT a good brother. He brought his smaller sibling to a place they didn't fit in and were miserable, they tried to fit in, Philip did his best to fit in, to point of obsession and after Caleb betrayed all he stood for and walkedin and out from the demon realm, he had his escapism and Philip didn't So Philip put my trust in this figure he respected and did what they say to find out all this time they didn't believe in it and had safe heaven for themselves? with the thing, they said Philip should hate? Caleb.... really needs some explanations or else he was a bad brother.
Is the Journal even entirely Philip's? I doubt. I think it's an endited mess where Caleb started it they continued together and then Philip edited Caleb out.
For sure the ending will involve time travel to find out the truth.
I think when we will get Philip's POV we will have to rewatch the entire series with different eyes.
