A shocking accusation could make it impossible for Jenelle Evans to gain full-custody of her son. In a Teen Mom 2 sneak peek, Jenelle's mother Barbara accused her of brainwashing Jace.
In the season finale clip, Barbara refused to pick up her grandson from Jenelle's home.
"Then give him back to me because it's been six years," Jenelle, 24, said. "I want to know why I am not allowed to have my son back. Why can I not have custody? Please tell me a reason right now."
Babs responded, "I'll tell you one reason right now. Boyfriend David Eason is controlling you and he thinks he's going to take control of Jace. This is between me and you and Jace."
When Barbara called Jenelle's boyfriend "crazy," the reality star fired, "He's not crazy you idiot! He didn't have me go to court. Before I met David I was bringing you to court."
Jenelle then explained how Jace has asked why he isn't living with his mother yet.
"Cause you're brainwashing him again!" Barbara said. "That's what you guys are putting in his f**king brain."
