Time is of the essence for Jackson, the little boy who desperately needs a new liver. He’s put on an experimental dialysis treatment but if he doesn’t get new organs in the next 24 hours, he’s going to die. We know Dr. Miranda Bailey can’t let that happen.
Things are also critical for serial killer William Dunn. He’s caused severe damage after attempting to kill himself. At first he begs Meredith not to page Derek. He wants to die at Seattle Grace instead of being executed in prison. But as death nears, William loses his nerve. He wants to live.
