Marcella disease: what’s wrong with her?

Marcella has a type of dissociative identity disorder (DID) that causes her to suffer violent power outages.

In moments of intense stress, she enters an amnesic state.

As a result, Marcella does and says things that she later cannot remember.

Actress Anna Friel has stated that the series is a drama and not a documentary.

Therefore, it should not be a precise representation of the fault.

In the fourth episode, Marcella has a violent encounter with Bobby who almost suffocates her while driving him to the airport.

Suddenly a car appears out of nowhere that saves Marcella from possible death.

Marcella suffers from shock and a mental fugue.

Disoriented and shocked, she returns to the Maguire family – but their mangled and confused explanation of what happened leaves Katherine and Finn in doubt.

Marcella Disease: Is It a Real Disorder?

Yes, Marcella has a real illness.

Between 0.5 and 3 percent of the UK population will suffer from some form of dissociation at some point in their life.

This means that it could affect almost two million people in the UK.

Even so, not much is known about them.

DID is almost always rooted in childhood trauma.

It’s also linked to PTSD – post-traumatic stress disorder.

The disorder can be treated.

In Marcella’s case, the disorder appears to have set in after the death of her young daughter Juliet.

Marcella is considered dead and is now working undercover.

She infiltrates a criminal family in Belfast and is known by her code name Keira.

But with Marcella it’s never been so easy …

The undercover cop begins to enjoy the family’s luxury life a little too much and begins to become part of the Maguire world.

Viewers watch her run into Maguire Matriarch Katherine, played by Amanda Burton.

Is Keira / Marcella striving to take full control of the family?

Does she even want her old life back?

Viewers can watch the third series as a stand-alone series without having seen series one and two.

Marcella series three, episode four: what happens?

In the fourth episode of Marcella, the undercover cop – aka Keira – struggles with her sanity.

She suffers extreme guilt following Danny Armstrong’s death.

She is tormented by flashbacks that put her in one of her joint states.

In a dramatic car scene, Marcella fights for her life and Bobby is “arrested”.

Meanwhile, Katherine Maguire warns Marcella sharply.

There are also some murders when someone wants to play Body Count Bingo!

The fourth episode of Marcella will air Tuesday, February 9, 2021 at 9 p.m. on ITV.
