No one mentioned the sister's (spoiler)

I checked and there wasn't a thread about the sister calling Child Protective Services on her sister and brother-in-law. Even though things worked out, I would imagine the relationship between them will be quite strained.

I was frustrated with the sister throughout the movie and I'm a Christian. She was quite pushy and nasty about the son's upbringing. That is not the way to introduce anyone to God or church. Anyway when she started snooping to find out if the sister lied!! By that time, I was livid. I understand who feeling used but I agreed with her husband. It wasn't her choice. I would've tried to sit my sister down to convince her to stay or something but I don't think I could've called Ms Bowers. At least not without telling them that I did so.
