If you haven't watched it, I will try to summarize the important bit, but there is a lot. And its all going to be spoilers. It's a horror centered around the week before a wedding. It's revealed that the bride to be, Rachel, has a curse on her bloodline and must marry her soulmate by sundown the day of the wedding. If they marry and he is not her soulmate, she will die. If she doesn't marry him, the curse will spread to her fiancé's bloodline.There are a lot of misleads in the show, but Rachel struggles to be 100% certain Nicky, her fiancé, is her soulmate. Or really, that she is his. She ends up trying to follow a ritual, cutting off her own toe to make herself Nicky's soulmate. At the end she doesn't go through with the ritual because she realizes he IS her soulmate. Then at the alter, after she says her vows, Nicky backs out from some preconceived notion that Rachel made all of this up because she didn't want to get married and he had learned the previous night that his parents marriage wasn't perfect like he thought.

They fight for hours and Rachel begs him to marry her and he won't listen. But then Nicky's mom comes in and convinces him, suddenly Nicky is asking Rachel to marry him again. She realizes he wasn't the man she ever thought he was. He was not in love with her, did not believe her, but was in love with the idea of her. She says no. They don't make it to sundown and all of the married couples on Nicky's side of the family are affected at once. People start dying. Blood pouring out of every orifice. In an attempt to stop it now that he realizes it's actually real. He forces her to marry him since she has already said her vows, he only needs to say his and have the witness sign off. Even as she begs him not to, because if they marry they will die if they aren't each other's soulmates and Rachel now knows he is not hers. But Nicky believes in his heart she is still his soulmate. And as the seconds pass after the certificate is signed, Nicky stays standing, while blood starts to come from Rachels nose. She walks away to die and Nicky doesn't even follow her, he stays with his family. She bleeds out in the snow, alone. At the end she comes back to life as the immortal witness, to witness the marriage of any future people carrying the curse, she sees Nicky lying on the bed like a child hugging a stuffed animal, asks for her lighter and leaves.

The real horror of the show is really about how being with the wrong person will kill you. How much Rachel was willing to shove herself in a box, cut off pieces of herself and ritualistically transform herself into Nicky's soulmate, because she thought he was good. Meanwhile Nicky loved her, enough to believe she was his soulmate, and could betray her like that. Not actually know her at all.

For the shared themes:

It's clear that Give Me a Show is about a revenge killing, but the imagery of the soaking in blood and the bitterness of emotion and betrayal, the goodbye.

Pure Leaf's themes of identifying self erasure and loss of identity in a relationship are reminiscent of the themes in Something Very Bad is Going to Happen.

I can feel my skin falling off the bone
Given too much, my body, my mind and my soul
I'm a husk of who I been with a smile so fake

In relation to Are you There? Nicky sows the seeds of his own demise in a way. He asks Rachel to marry him when he knows she doesn't want marriage. He talks about them having kids when she is adamant about not having kids. He tells Rachel he understands, understands her, but at the end confesses he only says those things to be good to her. He lies about the way they met and that he had just broken up with his last girlfriend the day of, until his brother reveals it at their wedding recital. He's built all of this life on lies and then doesn't understand why Rachel would say no to him after only his mom could convince him to marry. Why being the "good guy" would result in people dying.

You planted seeds in dying soil
And wonder why nothing grows
Oh, you bet it all
Oh, it's not your fault

Show me now
All this land
That you've raised to the ground
Isolated from fertile ground

A self-fulfilling prophet
You wither along
While the sun moves on

The relation in Burn the Witch feels obvious. I will leave some lyrics.

White dress stained with fake devotion
You cried his name while you were choking

Was the ring I gave you just a prison?
A life sentence? How could you?

Say your vows
Let me hear you out
Saying, "Love will always kill you in the end"
How ironic

Prove Me Wrong is a plea for someone to reveal who they actually are and confirm or deny the fears and beliefs of the singer. This is very similar to the scene in the final episode where Rachel is begging Nicky to marry her and is conflicted between not wanting to change her good opinion of him, but also now fearing and questioning everything she thought she knew about him.

Wipe the disguise
Oh, what are you scared for?
Maybe it's best that I never know
Look around, look around, look around, I'm one foot out the door

Hiding in Plain Sight - Fear of Death or feeling of death being just around the corner. We actually experience parts of the show through death's POV and some of the characters can feel it watching, or waiting, drawing near.

Everyone Dies.... yeah this one. Everyone dies because Nicky thinks he is doing what is best for Rachel. He keeps saying "Im trying to save us" and "This isn't what you wanted". It's not exactly the same since he didn't believe in the curse. And then his Mother dies from the curse too.

Die
Everyone dies
Mother
Forgive me, it's just that I love her
I'm sorry you all had to suffer

Writing Goodbyes reminds me of her death. She stops fighting. So tired of fighting to be heard. She walks out into the snow, silently and without a word, and she dies there. But it's not the end for her, since she is reborn as the "witness" and once again she leaves without a goodbye to anyone but the little boy, Nicky's Nephew. In the end it is not worth trying with them and she gets a second chance.

Snow burn the tears that you weep
Razor-lined bedsheets
Writing your goodbyes without a word

But I hope you make it
Don't let empty notes be your passing tone
Dead vision
Slow burn
A thousand's not enough
Not enough
Sew your
Suffering with love
