What a craptastic ending!  So, this entire story is filled with details about an inappropriate relationship between a kidnapper and his victim.  She agrees to go along with his plan to help him take her replacement, as she is getting too old.  Then, it ends in one of the worst possible ways.  The "filler story" in between, started okay, but then I realized I could have just watched random episodes of PLL, and had more answers.  Total disappointment.
