To me it sounds like she was frustrated with the case on TV, why are these two idiots bugging Judge Judy about this, it was an accident, accidents happen you suck it up and pay for it. Then used what happened with the two of you to elaborate on her position, as in she isn't dragging you to court just because you were there, her property her problem. The show just happened to be on when you happened over.
As for talking about the light being fixed, something was broken in her home and she told she was going to fix it, she got it fixed and was showing you "Oh look, it's been fixed!". I'd do something similar if say a friend had been over and my garbage disposal had broken, the next time they were over I might turn it on to say "Look it's fixed!" even if they had zero to do with it breaking in the first place.
