And now we have Jessie's death. The fact that she was ripped apart (thankfully, we're not shown this), as well as Evan's utter shell-shock at the incident makes things so much worse.
Jeff and Alex are dead now too, and Evan is completely possessed, leaving Vince as the last one left.
As of "WAKE UP," it turns out that Evan's not completely possessed...and HABIT left him to break down over the aftermath of what he did.
Evan entering the attic room where HABIT tortured his victims. He puts down the camera, determined not to broadcast his discovery...only to stagger back into the frame moments later, shellshocked. Then the audio cuts out, and we're treated to several minutes of Evan silently screaming and crying as he pounds his fists into the floor.
Evan remembering the atrocities he committed as HABIT. The anguish and self-loathing in his voice are nothing short of heartbreaking.
Worst of all is his confession that HABIT made him eat his own baby daughter. If you aren't numb with horror, you'll be in tears.
"All the life is gone. No more light. No more, no more remembering. (pause) I'm going to kill myself tomorrow... Thank you, but I think this monster's had enough. Bye."
One final kick in the teeth: based on Evan's memories, HABIT made Jeff cry and beg for his life...just like he promised he would.
"L'esprit de l'escalier". Evan visits Vinny during a period of clarity, and it becomes painfully clear that Vinny is destined to be HABIT's next victim—and there is nothing that either of them can do to prevent it.
Evan: Vinny...I tried.
Vinny: Tried what, Evan?
Evan: I tried to keep you safe.
Vinny: (puts a hand on Evan's shoulder) I don't think anything's gonna do it at this point, brother. (quietly) I'm sorry.
