Back in May, Jenelle Evans and David Eason lost custody of their children.
The move followed a Child Protective Services investigation that came in response to news that Eason had shot and killed the family dog.
After a grueling custody battle that lasted for several weeks, Jenelle and David regained custody of their kids -- or more accurately they regained custody of most of their kids.
Each has a son who's still being raised by someone else -- Jenelle's by Barbara Evans, and David's by his ex, Olivia Leedham.
Now, Olivia is concerned that David is coming for her child -- and she's asking fans to help her stop him.
Take a look:
1. David and Kaden

Many Teen Mom 2 followers might have forgotten that David has a son named Kaden from his relationship with Olivia Leedham.
2. The Forgotten Child

The reason for this, of course, is that Kaden has never appeared on the show, and is rarely mentioned by David or Jenelle.
3. A Little Backstory

Before he met Jenelle, David had children with two other women.
4. The Pre-Jenelle Days

12-year-old Maryssa is the product of his relationship with Whitney Johnson, and 5-year-old Kaden is the result of his time with Olivia.
5. Absentee Dad

For the majority of Kaden's life, David was not permitted to have any contact with the boy.
6. The Run-In

In fact, when Eason approached the child in a grocery store and hugged him back in 2016, he was promptly arrested.
