Episode Overview
Mike receives a distressing telegram from her sister Rebecca, revealing that their mother is seriously ill. She hurries to Boston with her children, the Coopers, where they encounter some skepticism from her own family about her unconventional parenting. While discussing her mother’s condition with the attending physician, Mike meets the charming and forward-thinking Dr. William Burke. Their differing opinions on her mother's diagnosis—Mike suspects hepatitis, while Dr. Hanson believes it's cancer—spark a collaboration, leading them to share a deep mutual respect. As they work together to help Mrs. Quinn and Dr. Burke’s patients, Matthew feels frustrated being away from Ingrid, Colleen enjoys the city's cultured vibe, and Brian is thrilled by the local candy shops. Just as they begin to settle into life in Boston, Sully makes an unexpected appearance, dressed in his buckskin attire.
