After Clarke Griffin was the last human in her dimension the Judge gave Clarke the chance to be with Lexa and Finn, Clarke without hesitation accepted. Clarke and her dog, Picasso were transported to a dimension where Lexa was reincarnated into Mary Brown and Finn reincarnated into Trevor. Lexa was the Heda and Clarke’s true love and Finn was Clarke’s first love both physically died 6 years ago.

Mary Brown was a 17 year old girl prophesied to become possessed by the devil when she turns 18 and become his soldier with unimaginable power. Mary’s mom is Susan Brown who is the devil’s servant, Jacob Brown is her Christian father, and Rebekah is Mary’s “evil” stepmom. Mary was raised in a Christian Amish-like community and forbidden to leave and forced to become a disciple of elder Beacon in an attempt to prevent the devil’s possession.

Mary has worsening seizure episodes and during those seizures she has demonic visions of the prophecy.

Mary was always a good daughter, innocent and a good church girl but she had a rebellious streak when it came to Trevor, sneaking off and being all romantic despite it being forbidden.

Now in the present Clarke was now 18 the same age as Lexa/Mary. Clarke appeared behind the glass aside Susan but Susan didn’t notice she was busy watching Lexa/Mary and Finn/Trevor making out as the clock ticked down to the midnight that would be Lexa/Mary’s 18th birthday. Seeing “Lexa” her true love making out with “Finn” her first love hurt Lexa wtf?!

Picasso whimpered as the clock struck midnight and Lexa/Mary pulled away and said to him Guess there’s some things that don’t change…

Lexa/Mary holds Finn/Trevor lovingly before her next words betray her demeanor and tone in a cruel way You really are stupid.

Even Clarke was alarmed by this. Trevor/Finn was confused as he said What?

Lexa/Mary snapped his neck with supernatural strength, her smile dropping into a dead inside expression as Susan looked at her daughter with pride. Clarke gasped in horror tears flowing down her face from her flooded eyes as she mustered out the trembling words Finn.

Lexa/Mary now possessed by the devil look passed at Clarke the Judge who was in the form of Costia now.

The Judge sighed I’m sorry Clarke, I can gave Mary her memories as her past life as Lexa even made her a Nightblood again but I can’t break the possession, this power is beyond me.

Clarke cried What? Why did you even bring me here if I just came to witness Lexa suffer a fate worse than death? You didn’t tell me Finn would die?! Is my pain a game to you?!

The Judge responded No it’s not, but I meant well. I didn’t know that…

Lexa/Mary’s eyes become pitch black, like inky black darkness, black holes. Lexa/Mary now the devil’s vessel interrupts the Judge Liar, you knew of the prophecy, you brought the girl anyway. You gave her hope to take it away. You are not evil but you’re not good and you’re not God, false one. This world is now mine. Begone hypocrite.

The Judge replied to the devil You’re kind would be dead if we had a means to kill you without you resurfacing in Hell.

Lexa/Mary smirked wickedly as the devil spoke through them Even your kind as limits alien, transcendence is a lie, the whole hivemind energy form bs, it’s not paradise it’s just the City of Light all over again. A false promise, a deception, a hollow paradise even you believe in. At least in hell there are no slaves.

The Judge was unphased You’re a worm, a sniveling snake who only hates, your freedom is selfish, it is damnation, you wanna be a god, my people take inspiration from God, we’re not perfect but we’re better than you in terms of purity, defiler.

Clarke tried to get through to Lexa/Mary Lexa please if you can hear me, come back to me. I just got you back I won’t lose you again.

The Judge said to Clarke It’s not too late I can take you and your dog home, you’ll be alone but this dimension is about to become Hell’s extension.

Clarke gritted her teeth with determination Go float yourself, I’m not leaving my Lexa, I’ll save her somehow!
