Jenelle's mother Barbara, puts it succinctly: "This is real nice -- to be a mother and end up in jail."

On the season finale of 'Teen Mom 2' (Tue., 10PM ET on MTV), Jenelle and her boyfriend Keiffer have been arrested for marijuana possession. She calls her mother and asks to be bailed out and return to Barbara's house and her son Jace.

"I guess you can come home, but I'm telling you this: If I find you with him one time you will be thrown out of the house, and you will not be allowed to come back."

Barbara adds, "I'm sick and tired of you putting this boyfriend of yours above everything in your life -- mainly your baby."

Jenelle seems compliant at first, but later helps Keiffer get out of jail.
