A simple push down the basement stairs imagine all that weight smashing down on a skull, neck, spine...ribcage.If you talk about Becky snapping, that won't happen. And if you are saying about her neck snapping that won't happen too, no rope can stand that weight, you might need a steel cable and some crane to do the job.
This talk made a thought come to my mind. How the hell could AOr Necky suicide? I'm not talking about their drug, food, but suicide at the moment. A bullet would miss their small brain, they would need thousands of painkillers because of their bodies, a rope would snap, a knife to their veins would find lard and nothing else, you must need a lot of poison too. And gas, well, just one Amber fart could be the equivalent of Zyklon B.
