The villainous Dr. Cherise Nuland mentions to Dr. Mariel Raphael, in the sanctuary and safety of the enclosed glass tea room, that hornets are reacting to a pheromone now introduced into Dr. Raphael. An insect is shown to land, however, it is a honeybee and not a hornet.
Incorrect.
Dr Mariel drink tea infused with chemicals, causing her sweat exude hornets pheromone. Usually, when hornet gets inside bee hive to steal honey, bees attack it in order to protect their house.
Since Dr Cherise mentioned that bees extincted twice within last decade, one may assume that their DNA been enhanced to better protect against competition, hence why they attacked "hornet" outside of hive.
Corbell Pickett's scenario to kill the bikers is extremely idiotic. It would take a very long time for the bikers to expire from heat stroke in the cars, and Pickett seems to be conducting his execution in the front parking lot of his dealership, where any passerby could see what he was doing. In addition, crucifying them in a public display would attract the attention of not only the local authorities, who he may have paid off, but of state and national authorities whose reach he could not escape.
The mother is on the bed blind while Flynne has the experimental drug in the needle in her hand. Her mother, who is at that time blind, turns to her and puts out her arm waiting for the needle. The question is how did she know the experimental drug was a needle if she was blind.
