Has Kate done this before (SPOILERS)?
I wasn't sure if Kate manipulated the whole scenario with Benoit from the beginning. Was there even a serial rapist on the loose as she stated in the beginning or was that just the premise she used to 'meet' Benoit? I started thinking about this after we see that she has lied about her father and she's not as naive as we were led to believe in the beginning.
Also, when Kate initially shows Benoit her scar from previously being attacked on the job I didn't think anything of it, but later after she's killed Benoit she deliberately injures herself to appear innocent--what if she did this before? She may be using her job to hunt men.
Unfortunately, the film doesn't delve into her past in any depth. Wouldn't the police and RCMP find it odd that she's now been seriously injured twice despite being so new on the job?
Too many things that didn't make sense in this film.
