Foreman finds Mary lying on a couch with Coach. Foreman apologizes for the whole moving-right-after-the-lumbar-puncture thing and says that it was all for naught since the tests didn't reveal anything. He says that they'll have to keep Mary overnight, and she starts to cry, and then apologizes for being so emotional. Yeah, Mary, why don't you turn off the waterworks, you pussy? Toughen up! Coach reassuringly (or suspiciously) rubs her arm and says that her parents' plane will be landing in just a few hours. Mary wipes her shameful tears away, and notices that they're red. She starts to freak, but Foreman checks it out and says those anti-meningitis drugs can turn tears red. It's not blood. The red stuff coming out of her mouth, however, is.
Mary gets an endoscopy. Chase explains that it will show them the source of her gastrointestinal bleeding. And by "them," he means the Cottages and big ol' crowd of patients who apparently have nothing better to do while roaming the halls than to stick their faces in another patient's business. I'm sure that, upon their eventual release, they'll be sure to slow their cars to a crawl at any and all traffic accident scenes, and I will be stuck behind them, cursing the day the DMV ever gave out licenses to people who never read the section of Miss Manners about the importance of respecting the privacy of people who have just been involved in a traumatic car accident and not causing traffic jams for the rest of us who did. The fact that Mary's crowd of observers are all perfectly able to crane their necks to get the best view of the unfortunate, scared child should prove right there that they don't have meningitis anyway, so Foreman might as well give them all blue slips while he tells them that it's not necessarily the best idea to crowd around the bed of a highly contagious patient. Chase inserts the tube. He can't find the source of Mary's bleeding, so they'll have to use something else.
Chase gives Mary a small pill-shaped camera to swallow, saying it will take a bunch of pictures as it travels through Mary's digestive system, allowing them to see parts of it that the endoscopy couldn't. That's really cool.
