Honestly it could be geno or it could be the zero point itself. Perhaps its no longer dormant and is searching realities to find things to help defend itself and the island. After all we know the zero point is sentient.
I said after the last update I wonder if the chapter 4 map will be a mixture of the 3 maps. Or maybe it’s just teasing a mixture of different random realities 🤷♂️
I’m guessing that maybeeee reality will break apart (once again) and we’ll travel through a bunch of different realities until we land on the reality with the new map
