What is the resolution?

Justin and Sheriff Jacobs arrive in time to save Cameryn and arrest Dr. Jewel because Dr. Moore called them after running tests that confirmed Cameryn's hypothesis. Later, Cameryn finally reads Hannah's letter, learning her mother left because she could not deal with the death of Cameryn's three-year-old twin sister. Cameryn did not know that she had a sister before reading the letter. Cameryn dials Hannah's phone number.
