Matthew Broderick’s character murders his daughter’s cat, in order to destroy evidence. They don’t show the actual killing, but he says “You gotta go,” and later he hands her a decorative urn. But then it’s revealed to have all been a lie and the cat is fine.
There's a dog in a car that is clearly in distress. Their tongue is curled and they are panting very heavily even though they're just sitting in the car. This is a clear sign of mental or heat stress.
The episode OPENS with strong flashing lights. It was some music video that some nuns were watching. After a minute or two (I didn't time it) their Mother Superior comes in and makes them stop the video. After that there's no more flashing.
