I'm sorry, Blames, the word you're looking for is thanks.

Lisa isn't saying it with the intent to get her brother in trouble, she's simply crediting him for her being happier not having to help. And even then, it's not a bad moment, because she isn't getting him in trouble on purpose, unlike the examples listed for the others, those four were being jerks intentionally, Lisa only wanted to thank Lincoln.
