S1E1 - At the ambulance, when he steps out to pee, he sees a dog, but the dog is dying. The dog has blood dripping out of its mouth, but it doesn’t die on camera.
A few episodes in, there's sleepwalking (dream is of dancing) that almost leads to walking off a cliff, but she wakes up in time. Unintentional, sort of like the dream in Anastasia. It happens again in episode 6.
When they fight in the ambulence, he gets injured in the neck. It's bloody and he doesn't make it. Around 43min. It will also be in the recap for episode 2.
There's nudity while changing and bathing, but it's not sexual or objectifying. Just people cleaning their bodies, without the male gaze / closeups and whatnot.
He falls underwater briefly, and the water's murky so it may be a bit scary (and unsanitary), but nothing bad happens. It's also not a natural body of water / it's flooded subway area.
S1E1 - A dog is seen near an ambulance with blood dripping from its mouth, but does not die on camera. Mice/Rats are seen running through the streets, and when the mass leaves, there are bloody mice/rat corpses left on the ground. Deer and mouse are the first dead animals shown, but are already dead.
S1E1 - There are a few animal corpses shown. The first is a bloody deer next to the side of the road, the second is a bloody mouse in the corner of a room.
S1E1 - The mother walks in to find her son dead in her bed with her also dead husband. Later in that same episode, a woman is seen wailing for help and carrying her dead son through the chaotic streets.
They discuss cancer in the office. One of them is a survivor, the other has a relative whose cancer was caught too late. They discuss mastectomies and doctors.
There is a scare (episode 5, I think?) where a pregnant person bleeds in a bathroom and they think that's what happened, but she's checked on by a doctor later and it was a false alarm.
