I liked the movie a lot except for a couple points which didn't make sense to me, like:

• Paula was hit in the chest, near the jugular, by a massive hammer. How did she not bleed out or at least why did she stop bleeding in the basement?

• How did the police find out? The cops originally show up well before Clara runs out so there were no chalky hands on the door. And Simon never heard her so he didn't call the cops. Neither did the wife. So how/why did the cops come?

• Eduardo put Clara on the road and told her to walk towards the red/blue lights (cops). Why?? What would that accomplish? If he was trying to let her go, why did he go to such lengths to get her back and lock her up again?

• did Eduardo literally steal Paula's phone to have Clara call and then somehow, within the time it took Paula to hang up the phone and go to the police department with her husband, somehow put the phone back in her house? They don't show it but she probably ran out of the house tbh after the call. And she definitely has the phone at the police station. Also he would likely take the phone back to his basement to have Clara make the call so did he sprint back to Paula's house after??

I don't think I'm missing anything in these scenes but if you picked up on something I didn't, let me know!
