The Caretaker has caught the illness from him. He decides to take care of the now "patient". It doesn't have to be illness or injury. Sometimes, it's when a parent used to take care of the child and, a few years later, the child takes care of the aging parent. May also happen to the Cloudcuckoolander's Minder if they take a blow to the head or visits Cloudcuckooland. This can be Truth in Television In many families with small children and a stay-at-home parent. It's not rare for the stay-at-home parent to get an infection from the kids before the parent who works outside the house. A typical ending of the Sick Episode. Compare to Now Let Me Carry You.
