What happened to Winnie after the jail break out in Tuck Everlasting?
When Winnie's parents realized how close they came to losing their child (when she ran away and the subsequent events), they began to communicate more openly with her. After she was found in the jail cell, she was returned to her parents' custody. At that point, I believe, she could explain her actions to her parents and be listened to seriously and with understanding. Soon after, Winnie's parents closed up the house, and the family was seen leaving town in their car to do some travelling. I believe, since Winnie never did drink the water Jessie brought her, the family bonded and shared a much more meaningful life. In the end, Winnie's tombstone revealed she returned to the town of Treegap, married, had children, and died at a ripe old age.
In the book Tuck EverlastingWinnie is released from jail to the custody of her parents. Her parents are shocked and question her over and over again. She finally is able to get through to her parents that the Tucks were her friends and she had done what she had to do to protect them.
Winnie is confined to her yard and not allowed to go anywhere. Winnie gives the toad the magic water. Winnie and her family had left their home and moved on. She grew-up to marry and have a family and was buried in the town cemetery.
