The finale picked up in the middle of their final bonfire, and after Kady once again declared that John made her not want to have kids because of how immature he is, they both decided to leave alone.
When they got back to the house they lived in in Texas, John revealed that he wanted to work on things and Kady was into it, right up until Kady told him she was going to visit Johnny in New York. So John kicked her out of the house and got a roommate, and said he occasionally talks to Katheryn, though she lives in Nashville.
Kady revealed that she and Johnny continued their relationship for a bit, but the distance was hard, and so the romance fizzled out. She now has her own apartment and no regrets. Her first Instagram post after the finale aired was of her and Johnny in a flashback post to their time on the island.
John, meanwhile, posted a picture of text reading, "Finally I can say it! I am a free and single man! 6 months too long," with the caption "Free atlast!"
