 FAIR: During the last surgery to reconnect the girls, the clock on  the wall remains the same time as the time of death of the girl that  died during the first surgery; 3:42. This would be an extremely  elementary mistake, particularly given that the passage of time  during the separation surgery, and the subsequent time of death, was  shown so explicitly. The frequency of the clocks appearance in the  second surgery, and its prominence in the shots, suggest that it is  not an error but rather a visual metaphor suggesting that time  stopped for both patients when one died.
