The goof item below may give away important plot points.
The plot revolves around everybody receiving injections of vitamin B12 to treat an exotic infection, and in the end Jordan refuses the shot, and Danny deduces from that that Jordan is pregnant (and thus did not want to expose her unborn baby to something that might cause birth defects). Several problems here. First, vitamin B12 does not treat any infectious diseases. (It's usually only used to treat vitamin B12 deficiency.) Second, vitamin B12 is not given as a shot. Third, vitamin B12 does not cause any birth defects. Thus, the writers got it wrong every step of the way.
