S4, E15: In attempt to bring some normalcy to his increasingly chaotic life, Charlie attempts to go the entire day without using his "special abilities." His vow is put to the test, however, when a superstitious farmer is admitted with a myriad of injuries, forcing Charlie to weigh his attachment to his promise over his attachment to his skills. Meanwhile, fearing for Dana’s outlook when she is confined to the hospital by her oncologist, Alex organizes a road trip north to Dana’s cabin for the annual cottage festival. But when Dana’s symptoms overcome her, Alex and the staff at the hospital must find another way for the senior Plastic Surgeon to save hope. Elsewhere, when Dawn’s college roommate’s life is put on the line after being bit by a spider, it is Zach who helps keep the situation under control with his vast knowledge of spider anti-venoms and Dawn’s knowledge of 19th century fiction.
