The taxi and one more spoiler question
Why did he want to drive the taxi himself? Was there any reason for that?
Second question
At the climax of the film, Dr Gramm thinks back and we see short flashbacks of things Lauren did. There is a scene where she walks into an appartment and kisses another girl. We see that the rope, she uses to tie her victims up, is lying by the door. Is that other girl Sarah Pollard.
