Keeping My Fingers Crossed

clark has been off the oxygen pump all day today. he just has to make it through the night in order for the doctors to discharge him from the hospital tomorrow. nighttime is the worst time for clark's oxygen saturation levels because he sleeps and gets all relaxed and his breathing gets more shallow. then he has less oxygen in his blood.

i'm hopeful that clark will make it through the night without needing to be put back on oxygen, but i don't think we're at all in the clear. tune in tomorrow to find out what happens with this cliff hanger!
