Finding Carter is about to air its season finale with a wild twist on something that Carter discovers about her fake mother.

Chatter On Crash Shooting Incident On 'Finding Carter'

While Lori Stevens is known as the woman who kidnapped Carter when she was a child and raised her as her daughter, some may have assumed that's all she was- a kidnapper. But as it turns out, she is going to be suspected as a stalker too.

On Monday, TV Line posted a sneak peek of the finale where Carter looks at pictures of her biological parents where her mother is pregnant. Someone took these photos where the parents didn't realize it, and they naturally suspect that Lori did it. But the pictures were taken before David and Elizabeth even knew her, which makes everyone confused.

All of the hints seem to make Lori the leading suspect, which Carter says is "creepy." The parents try to discover what had happened and they mention that when Lori first moved into the neighborhood, she probably did it just so she could be near them.

Elizabeth goes on about how she let the woman into her home and let her play with the kids without knowing what she was going to do.

The moment gets even more intense when Carter tells Elizabeth that she should continue her search for Lori- and she wants to help her out.

Check out the dramatic sneak peek here.

Finding Carter airs on Tuesdays at 10 p.m. ET on MTV.
