I really dont like this "sci-fi" turn of the story in this episode. I really hope this is somehow in elliots mind (which is a strong possibility) according to the story so far. I mean the whole parallel worlds theory makes Elliots struggle so far, a bit pointless. If thats the case ,Whiteroses machine worked ,so the Congo project cancelation was a bit pointless too. Mr Robot so far had logical and humble explanations to give about the acts of the protagonists .From child abuse to multiple personalities disorder all makes common sense, but this goes beyond the reasoning so far. I really want Elliots struggle to end with his innermost effort and not with some ex machina trick from a plot we all missed from the beginning. I really hope this is a trick Whiterose pulled like in Angelas case and Sam wants to make us believe in it like Angela did ,because otherwise it is a bit ruined for me .
