We Need To Talk About That Bizarre 'Deadly Illusions' Ending

Mary may be a famous author, but as a narrator, she seems pretty unreliable. Although fans see scenes of her getting intimate with Grace, there's a chance Mary never actually engaged in any sort of physical affair with her nanny. Considering Mary's writing an erotic novel, she could have just been fantasizing about hooking up with Grace and the steamy clips viewers see are actually just scenes Mary's envisioning for her book.

That said, it's obvious the two had a strong bond that was borderline inappropriate (assuming at least the sunscreen and lingerie shopping scenes actually happened) prior to potentially engaging in any type of sexual activity.

As Mary develops a relationship with Grace, it appears Grace is also getting close with Mary's husband, Tom (Dermot Mulroney). At one point, Mary "catches" Grace and Tom engaging in BDSM in the kitchen. That said, this could just be another case of Mary's imagination skewing reality.

While it's unclear whether Tom and Grace actually hooked up, there's reason to believe something happened. When Grace attacks Tom in the shower, he says he doesn't want to play games with her "anymore," indicating he once did want to play games with her. Further, once Mary arrives to rescue him, he says Graced seduced him.

This is one of the questions that was at least somewhat answered in the movie. In an effort to learn the truth about Grace, Mary visits Grace's aunt and learns Grace developed an alternate personality named Margaret due to her traumatic childhood. In a flashback, viewers see a young Grace trapped in a home and chained to a bed. The details are a little unclear, but by adopting the Margaret personality, Grace was somehow able to escape the imprisonment as a child.

It's Grace's "Margaret" personality who attacks Tom in the shower during one of the final scenes of the film, and presumably carries out most of Grace's misdeeds.

When Mary goes to visit Elaine after a fight, she discovers her friend has been murdered. The weapon, she realizes, is a pair of scissors from her home. After being detained by police and questioned as the prime suspect in her friend's death, Mary's quickly released. While the person behind the murder is one of the big mysteries left unanswered, there's reason to believe Mary didn't kill Elaine. First of all, at the end of the film, she visits her friend's grave and dedicates her book to her. Secondly, she was presumably never convicted of a crime.

More likely, Grace killed Elaine. In the scene when she attacks Tom in the shower, Grace (whose dangerous Margaret personality is in control) is seen in a tan trench coat, leather gloves, and heels, which is what the person who murdered Elaine was wearing, according to security camera footage. Perhaps that getup is what she wears when committing crimes?

In the very last scene after Mary visits Grace at the hospital, a woman wearing the same outfit as Elaine's killer is seen walking away. While viewers know the clothing is Mary's (she was seen wearing that jacket, jeans, shoes, and scarf when entering the hospital), the woman exiting wears the scarf over her hair and sunglasses over her eyes to hide her identity, just like Elaine's murderer did.

This could mean either Mary really did kill Elaine... Or, Grace killed/attacked Mary when she came to visit her in the hospital and escaped in the same getup she killed Elaine in. Considering both women have an affinity for that tan jacket, it could go either way.

One of the more bizarre theories circling social media is that Grace doesn't exist... or at least not the version that hooks up with Mary and attacks Tom. On March 20, the film's writer and director Anna Elizabeth James retweeted a tweet that said "What if this is just playing out the plot of her book?" So maybe Mary just used Grace as her muse and none of the really horrible stuff actually happened IRL. Perhaps it was all just a delusion in her mind as part of her writing process.

While there's no word as of March 23 about a Deadly Illusions sequel, at least one of the actors seems to think it's a good idea. Melissa Chambers, who played Grace's Aunt Lotty, tweeted her theory that Grace/Margaret killed Mary and escaped the hospital to kill again. She ended her tweet (which James liked) with a reference to "Deadly Illusions 2," which could mean if a second film happened, there might be more to Grace's story.

Deadly Illusions is streaming now on Netflix.
