Washington DC Abandoned?
The previous film ended with the White House surrounded by thousands of creatures and Umbrella trying to stop them. Yet at the start of this film the city is deserted and Alice is alone and desperate to find water to drink and she is spooked by a zombie that jumps out of the water which is 'for some reason' chained up.
1. What happened to her friends, the hoards of zombies around the building, and the Umbrella forces? Did they all just wipe each other out?
2. How much time has passed since the previous film?
3. Why was that zombie chained up like a zoo animal?
