A worried partner
Of course, Jeremy didn’t want to hold her a captive! Why would he want to do something like that? He’s a guy who is far too polite. When asked about the hostage scenario, he told authorities he didn’t want her to run into any strangers rather than stating the truth. He confined her inside the house because of this.
Oh, and his logic improves even more. When asked why he took her gun, he replied he thought she was going to kill herself. We have to admit, that Jeremy is a unique individual.
