Okay so obviously Michael was in another room when the film reel mentioned not to use the computer for anything other than it's original purpose =/
Favorite line of last night's ep What are you gonna do beat me w/ your Jesus stick?!?
Yeah, he wasn't there to see that part of the video... so, then, why is he hiding the fact that he's communicating with "walt"?
i think he knows venturing out to get walt from the others isn't gonna be a group thing, so he's being sneaky about it. as we see from the preview of the next ep. he runs off with some firepower to get his "boy" back, ALONE. that's when the "hunting party" goes after him.
