In the next episode of "Mom," Bonnie (Allison Janney) gets offended when her brother calls Adam (David Fichtner) instead of her when he gets arrested.

The synopsis and promotional photos for the upcoming installment, which is titled "Teenage Vampires and a White Russian," were just released recently, and they show Bonnie confronting her sibling Ray (Leonard Roberts) at the front of her house.

Apparently, when Ray got arrested by the police, he rather chose Bonnie's boyfriend Adam to get him out of jail. Now, Bonnie seems to be a bit disappointed because she always thought that they were very close and that they could rely on each other. However, now it appears that Ray has hurt that sibling bond between them. Bonnie is not giving him a welcoming smile and continues to talk to him at the front door. It remains to be seen what reason Ray would have to sneak around Bonnie.

In the meantime, Christy (Anna Faris) gets fired from her job at the restaurant. She appears to be confiding with her mom Bonnie about her sudden bad news. Bonnie is always there to console her daughter, but it is likely not without any hint of sarcasm. She is known to be a bit feisty with the people around her. They go to their support group to vent their problems at them. It remains to be seen if their friends will be able to give them some sound advice.

In the last episode, the ladies in the support group tracked down the culprit who stole personal belongings from them. However, it was the grandson of one of their members. They confronted the grandma who apologized for the theft. She later returned everything that her grandson stole.

"Mom" season 5 episode 9 will hit the airwaves on Thursday, Jan. 4, at 9 p.m. EST on CBS.
