Last night's season premiere of Teen Mom 2 was drama-filled, to say the least, but arguably the most shocking moment of all came when Jenelle Evans' second baby daddy, Nathan Griffith, accused her husband of putting his hands on Kaiser. "He told me David [Eason] punched him one time," Nathan said of the three-year-old. "It does seem he has tendencies to be a violent person."

On this week's episode, Jenelle sobbed when she found out Nathan's mom, Doris Davidson, had filed for emergency custody. "Nathan's mom tried to file emergency custody on me to take Kaiser away immediately," she said. "She said she was worried about the bruises he comes over her house with. I told my lawyer Kaiser came home with finger bruises on his butt from being spanked. Don't go behind my back and file emergency custody."

According to court documents, Doris alleged that Kaiser was being abused and claimed she witnessed "bruising and markings on the minor child that are unusual and more than normal." She also stated that Jenelle and Nathan were unfit to care for the little boy.

Meanwhile, Jenelle blamed her tumultuous relationship with her mother, Barbara Evans, for teaming up with Doris. "I'm pissed off. Jace tells me the other day Kaiser pulled his diaper down and had poop and David got mad and was spanking him so hard," Babs said. "Jenelle says it's a lie. Jenelle always protects the man she's with. She's putting this guy again over her children."

And protect him, she did. In response, Jenelle told cameras, "He doesn't touch the kids like that. David punches Kaiser in the face. He plays around! That's what Kaiser means. She's taking this out of proportion. Everything is fine and everyone else thinks it's not."
