Headscratchers / Halo: Nightfall

• The Covenant Anti-Human Element is pretty lame. It kills a number of human beings on Sedrans from children to adults but doesn't actually kill all that many since the entire planet isn't wiped out or anything similar. A biological weapon would do much more or even a conventional nuke. So, why is everyone actually concerned about this to the point of going to a Halo fragment to destroy it?
  • Presumably, the worry is that someone smart will eventually develop it into something more lethal.

• The Tug is a "two-man vehicle" but it carried a horse with them. Why couldn't the rest of the team have traveled in the horse stall?
  • Probably because the horses weren't going to be brought back the smugglers. The horse stall is extremely damaged, and there's no guarantee it was gonna be fixed.
