S11, E12: When a 16-year-old girl who had received a kidney transplant from her father arrives at the emergency room feeling dizzy, Carter traces the problem to a new drug that the girl was taking to control seizures related to her kidney dysfunction. Her father feels guilty because he pushed for her to take the new drug, and its side effects may force his daughter to go back on dialysis. The doctor who prescribed the medication, Dr. George Henry (Chad Lowe - "Life Goes On"), is Carter's former student. Carter asks Neela to post information about the drug's side effects on the Internet, which causes an uproar when the pharmaceutical company finds out. After Abby and Neela complain about their lackluster dating lives, they are assigned to work with Jake (recurring guest star Eion Bailey - "Almost Famous," "Band of Brothers") and Kovac--men they each find attractive.
