S10, E9: Two distinctive cultures commingle when Neela treats two Amish teenagers who were in a car accident and are exploring the outside world to determine if they want to return to their reclusive society. Corday and a few others mourn the loss of a talented colleague. Meanwhile, Sam clashes with sympathetic Kovac after he gives too much attention to her trouble-prone teenaged son, Alex (recurring guest star Oliver Davis). Lewis becomes upset when an unconscious 5-year-old girl cannot be traced to any parent or guardian. And Pratt notices the beautiful Valerie (recurring guest star Joy Bryant), who is visiting her nervous brother Gallant.
