The doctors have determined that Will did pick up an infection, probably in his breathing tube. The one they have in mind likes warm, moist places, so a breathing tube through which warm, moist air is pumped would seem to be an ideal breeding ground. Because they caught it quick and gave him antibiotics, he should recover just fine. That might explain his recent dip, and the fact that he seems to be doing much better today. As for the eating, let's just say we know it's going in OK. We're just, um... waiting to see when it will come out. In the grand scheme of things, I'll take that problem over breathing problems any day. Per the usual, they are watching a whole host of things, constantly tweaking each of the things he gets as they react to (and anticipate) changes to his system. One of the doctors referred to it once as a "tune up," though it seems more like plate spinning at times.
