I've read that there is some kind of theme going with the electrical wiring. Recall the first episode and the head of the Migeral (sp?) corporation killed himself by using the emergency electrical shock device while sitting on the toilet? He put the wiring in his mouth and was electrocuted. Then we saw Walt put the ricin poison behind the electric panel in his bedroom, then Walt using an electrical cord to cut the handcuff off his wrist to escape last week.....is this a foreshadowing of some sort?
Were any of you shocked that Walt reveals that he has been monitoring this company that he lost an investment in years ago called Grey Matters. I had forgotten all about that back story. Is Walt going to go off on them? Will he buy them out? I have no idea where all of this is going at this point.
