In the scene w/Stephen Weber and the alien POW, did Weber say something about the skitter having dilated irises or some other odd symptom before they cut away from that scene? I got the impression that Weber might have been on the verge of discovering that the skitter was drug addicted just like the kids. And going through withdrawl would explain why the skitter went berzerk and killed Weber. (In addition to wanting to escape of course...)
Weber mentioned something about "rapid blinking". The one thing that kind of dissapointed me was the fact that in the last episode when the kid latched his harness bck on - in effect the Skitter was speaking through him. Given they want to learn more; I'm surprised there was no follow up or any attempt made to directly communicate via that method for a short time.
The other thing about the first kid freed: He seemed not to remember a thing, or recognize his father; yet at the end of this episode, oonce Ben wakes up, the first words out of his mouth are "Dad?" Just wondering why one kid's memory would be impaired to a massive degree; yet Ben's memory appears inract.
Still overall, I like the series and the fact they haven't done any real spoonfeeding of info to the audience as yet.
