I really don't see the problem with it being one zombie, there is about a 6 to 12 hour gap between Samatha's death and Datu's rescue, more than enough time for TOwM to get to the tower.

SPOILERS



The bigger mystery is why didn't TOwM's call in the zombies right away after breaching the Tower, like he did in the other tower. In CJ's tower he walked in the front door and called them in.

In the Tower, he gained enter, killed Paul and then proceeded to knock on a door, that doesn't fit his MO of calling in reinforcements right off the bat.

And if I got my estimates right, The Tower had about 2 less occupants then the CJ's tower, which lost 3 out of 30 right before the attack.

If this is in the wrong area, tell me or if this has been answered, I would love to know, it's been bugging me for awhile.
