Both protégé's stories hit close to home for Kandi this week. In her most emotional challenge yet, she mentors Cory, a talented 18-year-old theater geek who suffers from Autism, Tourette's syndrome, ADD, and OCD. Cory is determined to overcome the odds, prove everything wrong and launch a music career with his soaring vocals. Up against Cory is Kristin, a stunning 25-year-old who is trying to fulfill her lifelong promise to pursue her musical dreams she made to her brother who died in a tragic accident. She decides to channel the pain into a heartbreaking ballad called "If You Were Here." Will Kristin be able to deliver the emotional performance the song deserves?
