WHO CAN SEE CAPTAIN GREGG?
Children see and hear many things that adults seem to have lost the ability to experience. Ditto for animals. Jonathan was able to see the Captain from the very beginning, as was his pet dog, Scruffy. Jonathan’s older sister, Candy, however, was unaware of the Captain’s presence until the second season. How and when she was introduced to Captain Gregg was not explained. In the case of adults, the Captain makes his presence known only to those whom he so desires to be seen by. Claymore Gregg (unfortunately for him) is aware of the Captain’s existence. Carolyn was introduced to the Captain shortly after arriving in Gull Cottage, while Martha didn’t meet the Captain until much later during the show’s second season.
