On “Invest in Love”, a young Doogie Houser type patient of Arizona’s, Wallace, has been in the hospital for the past 7 months. Wallace’s very wealthy parents present Arizona with a hefty birthday gift of a $25 million donation for additional research into their child’s condition. However the patient’s condition worsens and Arizona doesn’t want to do another surgery since Wallace is not strong enough. The father (and donor) are insistent that Arizona needs to do the surgery to ”buy Wallace more time.” Even though it’s only a couple of months. By performing the surgery – Wallace dies.
