The ending of this one was a big disappointment, imo. JJ. just wakes up in a pool of blood, apparently saved by a freaking defibrillator, as if that magically puts blood back in your veins, and hey! Emily's there all of a sudden! And then the paramedic just leaves. They leave the person who just tried to kill themselves in a pool of their own blood, like "my job here is done." Heck no it isn't!
A very simple way to improve the ending would have been them briefly flashing to the paramedics finding her where she tried to kill herself, Emily arriving as she's carted off to an ambulance. Then skip to her waking up in a hospital bed, with Emily there with her. Easy peasy, less ridiculous ending.
