7 Ways To Defeat Diana Walter In Lights Out

7. A Bullet To The Head

Let's start with the least creative and most reckless method of dealing with Diana, which is unsurprisingly the one the film eventually relies on.

Towards the midpoint of the movie we come to learn that there is a definite connection between Diana and Rebecca's mother, Sophie. In fact, the two actually met one another at the Mulberry Hill mental institute where Sophie was being treated for her depressive personality disorder. Before her unfortunate demise, Diana became quite transfixed on young Sophie, doing everything in her power to prevent her from recovering and leaving Mulberry Hill forever. Simply put, Diana didn't want to be alone again, and thus acted out whenever something threatened to break this relationship between her and Sophie.

Unfortunately for Sophie, death didn't put an end to Diana's psychopathic behaviour, but rather worsened it. After realizing that her and Diana are still tethered, Sophie decides to sever this connection once and for all before Diana is able to wreak further havoc on her family. With a self-inflicted bullet wound to the head, Sophie ends up defeating Diana for what we are led to believe is the final time.

So if you're being stalked by a shadowy figure tethered to one of your family members, you know exactly what to do. This is the only way to end the curse for good.

Pros:

Since there seems to be no sequel to Lights Out on the horizon, it's clear that this method worked, with Rebecca and her boyfriend Bret being alive and well.

Cons:

In the real world death is pretty much the end, so you'll have to come to terms with sacrificing your relative. That said, depending on which family member we're talking about, this might even be a pro.
