Patience, I am probably silly to go into such detail here...
At the hotel based sleep lab, (remwood is right) there are only 2 patients, one in room 201, and one in room 202 and the tech is in room 203. I can see how you may have thought there were 3 patients since she types up 3 names in the "opening scene" and notices they are all from "farmville"
