Keep wondering then. I don't think you'll ever have an answer to that, considering the time it take for a scene to be upload..
I've sussed it out. Braindead is in a higher dimension where time elapses exponentially slower than it does in ours. Also, due to the complexity of that higher dimension nothing makes sense when squeezed down into our realities. A coherent story is simply not possible when you are missing an extra dimensional space.
But what the fuck do I know? I'm just a frog on a lilly pad, just trying to get through life without being swallowed by an alligator.
