- Does either pill actually do anything? 2 answers
When Neo takes the red pill all kinds of things start to happen. In the matrix the mirror turns into 'The Blob' and smothers his body, in the real world he claws his way through his pod membrane, a machine suddenly appears and grabs him and looks him over then the control cables are detach from his spine and he's flushed to the sewer. How does that work?
For clarification; The two other related questions' answers talk about placebos, metaphors, sleeping pills and finally "a program to wake Neo up". Good answers for the context of those questions but they all focused on 'Neo', no explanation to what physically happens and how it happened. Is it a virus designed to cause the machine nursemaid to 'abort' the infection?
