The manga has always been random and unpredictable, paths represents one of the final mysteries and we are just now getting concrete information on it.
Nothing was "asspulled" with it, everything being in done in paths is built upon premises and foundations he set up when he introduced it 80 chapters ago.
We've known it's a collection of all the shifters memories and that a shifter can unknowingly see these memories thanks to some kind of trigger.
We know have EZ actively exploring them.
We've known time doesn't pass the same while in paths, now we know zeke has been there for what feels like literal years.
We've known the FT can be accessed if a shifter of royal blood comes in contact with the FT.
What we didn't know was the only reason the FT listened to Erens will, is because dina wasn't sentient. So when he triggered it with Zeke, it was a slave to his will since he is sentient and has royal blood.
Every reveal, or current thing happening has been set up and foreshadowed one way or another.
Even Zeke being one step ahead it's just like when he lied about what someone looks like after he infects them. You bitching for bitchings sakes but not presenting any competent argument.
