Unpacking Mona’s "Sickness" in Pretty Little Liars

Mona Vanderwaal’s journey in Pretty Little Liars is marked by significant emotional and psychological turmoil. While not always physically ill, her "sickness" often manifested as mental distress, manipulative behavior, and periods of intense vulnerability. This complex portrayal made her one of the most compelling and unpredictable characters in the series.

Was Mona Always "A" in PLL?

Mona was revealed to be the original "A" in Pretty Little Liars. She masterminded the initial torment of the Liars, driven by a desire for revenge and a deep-seated insecurity. Her reign as "A" ended with her being committed to a mental institution after a near-fatal car accident.

Mona’s Mental Health Struggles and "A"

Mona’s descent into becoming "A" was deeply rooted in her struggles with mental health. After being bullied by Charlotte DiLaurentis, she developed a fractured psyche. This trauma fueled her obsession with tormenting Alison and, later, the other Liars.

Her actions as "A" were a twisted attempt to regain control and punish those she felt had wronged her. The show often depicted her isolation and paranoia, highlighting the severe impact of her experiences. This made her a sympathetic, albeit dangerous, figure.

The Impact of "A" on Mona’s Well-being

Being "A" took a significant toll on Mona. The constant secrecy and manipulation wore her down. Her eventual breakdown and commitment to Welby Psychiatric Hospital were direct consequences of the immense pressure and psychological damage she endured.

Even after her initial reveal, Mona remained a target and a pawn in various schemes. This continued exposure to danger and deception kept her in a state of constant anxiety and fear.

Was Mona Hospitalized in PLL?

Yes, Mona was hospitalized multiple times in Pretty Little Liars. Most notably, she was committed to Welby Psychiatric Hospital after her initial "A" activities were exposed. Later, she was also held captive and subjected to psychological torture by the "A.D." team.

These hospitalizations were often a result of her own actions or the machinations of others. They served to underscore the severe psychological toll her involvement in the "A" game took on her.

Mona’s Role After "A"

Even after stepping down as "A," Mona remained deeply entangled in the mysteries of Rosewood. She often acted as an unlikely ally to the Liars, using her insider knowledge of the "A" game to help them. However, her past actions and complex motivations meant she was never entirely free from suspicion.

Her strategic mind proved invaluable, but her past trauma and tendency towards manipulation meant her alliances were often precarious. She constantly battled her own demons while trying to protect her friends.

Mona’s Relationship with the Liars

Mona’s relationships with the Liars were complex and evolving. Initially their tormentor, she later became a reluctant confidante and protector. Her bond with Hanna Marin was particularly significant, showcasing a deep, albeit sometimes strained, friendship.

Despite her past, the Liars eventually learned to trust Mona, recognizing her genuine desire to help and her shared experience of being targeted. This evolution of trust was a key theme in her character arc.
