Alright, who’s ready to get emotional over Until Dawn again, because I just realized something.
I don’t think Beth Washington died immediately.
When Sam and Mike find Hannah’s journal in the mines, the first entry tells us that the fall killed Beth, leaving Hannah alone and trapped. The fall killed her, not she died in the fall. And the next sentence? I watched the color drain from her face. The blood draining from someone’s face is something that happens immediately after death, since the blood stops circulating as soon as the heart stops pumping it, and Hannah saw this happen. Considering the fact that she seemed to be in pretty bad shape herself directly after the fall, looking stunned or unconscious in the close-up of them lying there, we can probably assume that she wouldn’t have been able to sit/stand and see Beth (who fell behind her) for a while after that.
Beth’s injuries from the fall may have killed her, but everything points to this being somewhat drawn-out rather than instant. Hannah had to actually watch the moment life drained out of her little sister. What if she was conscious? What if she had the chance to say something to Hannah before she died, to comfort her or make an ‘if I don’t make it’ speech? What if Hannah was holding her, trying to tell her it would be okay? Why does my heart hurt so much?
