New update. Isaac's using his Titan-given talents. However, I'm confused on something. Isn't the portal to Spacerock already closed? It fizzled when the tower fell and took Cubbins with it, leading to that trick of Jack's with the severed head. And yet, Isaac mentioned a "portal to Jetstone" that is presumably still an option, given that he warns against it. Where, then, is this portal?
