Things have already been tense for the Return to Amish gang thanks to the difficulties Rebecca and Abe have been having when it comes to trusting if Sabrina will stay clean, but the arrival of another person in New York is going to only add to the issues threatening the group.

Rebecca, Abe, Sabrina, Jeremiah and Mary all traveled to New York to crash with Kate for a few weeks, and Mary, who still feels a little out of her element since she was banished from her church, asked her daughter Esther to come to New York as well to help her as she adjusts. However, the move is one that won't be seen too favorable by her son or daughter-in-law, who appear to have some issues with Esther.

Rebecca will mainly feel the tension with Esther, and may even question if she really came to New York for Mary, or if she decided to use the situation to her advantage and experience life the way the rest of them did when they came to New York for the first time a few years ago.

Meanwhile, Abe and Rebecca's marriage, which has already suffered some strain because of Abe continually being on the road most of the time for work, will be dealt another blow when an unexpected extra cost forces Abe to potentially give up on some of his Amish traditions he wants to keep within his family.

Abe will learn he needs extensive dental work, but it comes with a hefty price tag of over $20,000, money he and Rebecca simply don't have. And when Rebecca decides to get a job to help cover the expense, it will possibly cause a problem since Abe has tried to keep to the strict standard of his wife not working, as per Amish traditions.
