Colleen's girlfriends who are young teenagers know how old Abigail was when she married Sully. They married years before. It is unrealistic to expect these young girls to know this fact.
Sully visits the cabin to warn that the storm will drop the temperature quickly. There is the sound of rain and wind in the background. Sully is not wearing a hat. His hair is dry and well-groomed.
Water submersion is not the mandatory treatment for frostbite.
Not quite sure how anyone could get frostbite. All the trees and grass are green with no snow on the ground and no frosted breath.
Hank would have needed a dewormer to be purged of his worms, but they were not available back then.
Colleen went to the post office to pick up a very special and valuable gift for Dr. Quinn. She leaves the stethoscope and carrying box behind. There is no evidence that the items were retrieved or delivered.
Colleen stops by the post office for a long awaited package. It contains a prized gift for Dr. Quinn. She gets distracted by a romance story. She leaves the box on the counter and the stethoscope on the bench outside of the post office. Colleen is too serious a person to leave such a valuable and special gift behind.
Colleen is trapped in a shed during a rain storm. There is a severe wind and rain. No snow. An icicle develops. Colleen is wearing a shawl and an apron. It does not make sense that she did not use the shawl or apron to protect her hands. Colleen developed frost bite. It does not make sense.
Dr. Quinn tells the towns folk that Colleen developed frost bite due to the wind at high elevations. Not realistic.
