They are making it look like it's the same skitter with the one red eye thing. It was definitely the same one with the tracking worm thingy - eww. I'm glad they are going to meet up with a larger group that is organized and has a government going. It wasn't really going anywhere as it is. This will open up new storylines.
So, here's probably a stupid question: the skitter's on the ground look like spider/monsters, but the thing in the spaceship looked totally different. Did they say why and I missed it? Are the spider things another race that they picked up on another planet and harnessed?
