I wish I could've seen the adoptive mom...
...beat her sister's ass after what she did!
What a horrible sister! I'm not at all close with either of my sisters (we were raised in different, distant households) but I would have never betrayed them the way she did. It would be one thing if she really did feel like the child's interest was at stake, or if she was trying to save her sister from making a big mistake, but that wasn't her agenda. If that was her true motive, she would have brought up the fact that she knew what they're real plan was BEFORE they left for Haiti. Why get the authorities involved before even talking to them and giving them the opportunity to change their minds? She could've at least notified that social worker lady before they left if she was too much of a coward to talk to her sister first.
You could especially tell she did it for selfish reasons when she was telling her husband about them. Her first complaint was "they used us, they used the church" not "OMG I'm never gonna see my sister and her family again" or "They're making a huge mistake". She was just mad they didn't tell her and used her righteous Christian attitude to justify her betrayal. I'm glad her husband at least had some sense.
