Assassin shows his two guns to the approaching crowd and tells them to stand back. If they still keep coming he will fire a warning shot.
Krusten will immediately try to run at her maximum and hide far from the being. When things settle she will meet back at the airport.
If Assassin is successful he will try to see the cause and fire warning shots only and get his bearings. If there is a deep lake or river nearby he will try to head there to get away.
Krusten will try to run in zig zags or whatever to throw off this being. She will also still check her intentions.
Assassin will first offer the driver double the fare, if he does not want to go then he will point the gun towards him and demand he be taken near to the airport.
Krusten continues with speed towards the airport slowing down only for directions. When she gets there she will stalk it for awhile and then enter casually and and check in for an early flight back home.
