Answer:
Jay's case is an example of dissociative fugue.
Marian's case is an example of dissociative amnesia.
Step-by-step explanation:
Both dissociative fugue and amnesia are ways of coping with extremely painful events. In the first case, the person commonly wanders away from home. All of a sudden, they realize they are in a complete different place, having no recollection of how or why they got there. As for the latter, the person usually forgets everything that took place in a certain period of time surrounding a traumatic event. Dissociative amnesia takes place when the person is not physically harmed, but has experienced pain and trauma.
