A woman is held at gunpoint.
The hand of a dead person is sawed off.
A man has a hook rammed into his chest and then is thrown to the shark whilst still alive.
Many adults die, don't know f they had kids. The one father and daughter duo survived, there is mention of the mother who had died from a sickness years before
Mostly happy. The survivors are safe, as long as they stay away from the water. But they realize what messed up their store has messed up the entire city.
You see a car crash into the store front. Another car swerves as the wave hit. Another car is rolled over. Neither crash is expanded on or shown in detail.
I can't say for sure but there is quite a large amount of cars going zip zap zoom all over the place so maybe there's a blink and you miss moment of someone being hit.
