In the episode, "A Night in Sickbay" of Star Trek: Enterprise, Captain Archer and others, including the dog Porthos, return to the ship and have to go through decon because of a pathogen. The decon doesn't work on Porthos, so Dr. Phlox has to take stronger measures... or so he says. A lot of this episode is about Porthos's medical emergency... if there were an emergency.
Did Dr. Phlox fake the whole thing to torment Archer? Phlox has a sadistic streak, revealed in another episode with this line: "I took an oath not to harm patients. I can inflict all the pain I want."
I'm thinking that this might have extended to inflicting mental discomfort, and that Phlox staged the whole thing as a dark joke on Archer. Is that correct?
