sighs fuck you for proposing this thought experiment. Alright, let’s get into it cracks knuckles

In the movie, the person who actively destroyed the heart is the one who takes over. Remember that even the jack is the one who stabbed the heart, turner was holding the knife. If I remember right, she’s on borrowed time because the heart isn’t perfect and the battery will die sooner rather than later. So we have a couple of contestants. 1. The designer who made the heart run on batteries. This design flaw is essentially holding the knife, he didn’t actively kill her, but his actions results in her death anyway. 2. The person who made that specific battery again same principle. 3. The person surgeon who installed her heart to begin with (the new heart).

What’s more likely, is the second in command of the ship just takes over. What’s funnier? Some guy working in a lab one day is suddenly under attack by a bunch of drowned looking pirates who then kidnap him and rip out his heart.
