I misused a phrasing there—mutually timelike regions can only be 1 dimensional or less, just as mutually spacelike regions can only be 3 or fewer dimensional.
Entanglement is between points that are spacelike separated, but the boundaries of this entanglement—the processes that create or destroy it—are purely causal and local.
We can continue in PM. I just wanted to clear that up, since I ended on something that was flat-out wrong.
