In Breaking Bad 1. What does it mean "little plug where the ashtray used to go" in this context? In the past, people were allowed to smoke on airplanes, so they had cigarette lighters in the armrests. I believe he was referring to those. 2. What does it mean "for his own good" in this context? It means He wants to beat the kid to death? If you do something "for someone's own good" it means that you are doing something that might be painful in the short run, but will be beneficial in the long run. Like if you pour alcohol on a wound to disinfect it. It is extremely painful, but it's for their own good because it helps clean the wound. It definitely doesn't mean he wants to beat the kid to death. It means that he wants to get his attention. He figuratively wants to hit him because he thinks he is making a big mistake.
