No, but the man in a couple has an extremely fiery temperament and is seen starting a fight with strangers over next to nothing. In one scene he makes a sudden outburst, slamming his hands on a table while his wife is next to him. She doesn't appear to be affected by his behaviour, so I guess she feels safe around him (and it seems that she actually has a calming effect on him), but I'm thinking it might be triggering to some anyway.
A woman says she takes Barbital (a barbiturate) literally all the time; we see several bottles of it on her night stand, and she's clearly very much under the influence.
There is an interaction where the assistant tells the old lady she brushed her dog earlier, and then she retorts she had actually 'tortured' him instead. I'm pretty sure it's just an exaggeration though meaning that she didn't do it exactly like she would want, instead of actual harm, based off the characters themselves and that the dog seems fine sitting next to them
Someone tries to take the blame for the murder and shoot themself to allow the case to be closed, but unbeknownst to them, the gun they use is not loaded.
It's only mentioned and shown briefly, but a child named Daisy Armstrong is kidnapped before the story begins, which prompts many of events in this movie.
Frequent mention is made to dead relatives and the affect their passing has had on the surviving family members. None of them die in the present timeline, but it’s still a big part of the film.
Willem Dafoe's character says things on several occasions that sound exactly like things a Nazi would say. There's other bad stuff as well; right now, I only remember someone talking about a mr. Marquez, saying stuff like "his kind aren't as averse to murder as we are". But there are at least vibes of classism and sexism as well.
