We need to know how the borderland operates . I wish they write a good plot for s04.

Is the ending some sign that there will be a global catastrophe = everyone goes to the boderland? Also I've always wondered why 'Alice', just thought it was a play on the original title, but they actually showed a lady at the end with the name Alice???

Saw some theories that Netflix may actually be cooking a western version and that season 3 actually leads to it with that discussion they have near the end about a lot of deaths coming in the near future + the ending which lets you think that there is gonna be a massive earthquake or something in  the US

It would make sense for Netflix to milk Alice in Borderlands. This would allow for a new cast in a more western setting that may reach a whole different kind of viewers that don't watch JDramas. Done right, this could be a huge success. And for us, it's more Alice in Borderlands and considering it's a sequel, it's not gonna butcher the original so it doesn't matter much
