It all started when curiosity got the best of me, and I decided to watch a YouTube video about what happens after Slendrina's death (Stick noodle edition). Basically, it started with two people, Diana and Gregory (Granny and Grandpa). Gregory took Diana to a mansion (from Granny 3), because Diana was sick with cancer. But Diana was worried about Angelene and her family, since (as she states), they haven't seen them for over a year. So, she asked Gregory is he could go check on them that evening. Gregory agreed and left Diana so she could rest. (She kept a baseball bat with her for protection). Slendrina's house was located in the middle of the forest, so Gregory had to walk for a while.

When he finally reached the house, night was already falling, so he went in the house. When he walked in, he was confused by the fact no one seemed to be there. So, he went to check Rina's (Slendrina's) room.

So, when he walked in Rina's room, he received the shock of his life. Rina was lying face down on the bed, with her left arm dangling off the edge. Her skin was a pale white, and her eyes were bloodshot and staring off at nothing. Veins were visible through her neck. Her diary was lying on the floor next to her. Gregory began to cry silently, which is actually sad with the music. He swooped and clutched Rina's arm, then gently lifted it up so it was out of the way. He then slowly and gently raised her head. Her mouth was hanging open, with blood dribbling out. When Gregory saw that she was dead, he put her head back down and turned away. He saw her diary and took it and left the room.

He arrived in the kitchen, where he saw a bottle of rat poison lying on its side, with its acid green liquid spilling out. He then went into Simon's (Slender Man) and Angelene's room.

He saw Simon lying on his back on the bed, dead. His skin was withered and pale. Gregory began to cry more, then sat on the end of the bed. He started to read Slendrina's diary at the recent date: that very day. It was the entry from Child of Slendrina, and various pictures were shown to shot what happened. When Gregory reached the end, he slowly turned furious. He slammed his hand through the air and said,

Gregory: "Damn it! All this time I thought I had a daughter, but in reality, I had a monster!"

The view was changed to somewhere in the woods, where Angelene was walking alone, void of any emotion at the moment. Then she said,

"I did what I had to."

She suddenly grabbed a rod and slowly walked forward, where a person was standing there, oblivious to Angelene. She killed him, then went back to the house to "Bury the bodies".

She entered the house, and Gregory just walked out of Angelene's and Simon's room. He saw here and said:

"There you are!"

Angelene was surprised and they started talking...

Angelene: "Father?!"

Gregory: "How could you have done this?! You will pay for what you did to your family!"

Angelene: "Father, just... Let me explain some stuff..."

Gregory crosses his arms and shakes his head.

Gregory: "There is no explanation for the hellish thing you've done."

He throws an arm up.

"I never knew I was raising a psychopath like you are!"

He then raises his cane and points it at Angelene.

"You will pay for what you've done."

Angelene suddenly gets angry.

Angelene: "You know what?"

She leans forward.

"Come on Father, show me what you got!"

She straightens and raises an arm.

"My life has been hellish ever since you and mother forced me into this toxic relationship with Simon!"

Gregory turns very angry and gets into a post. Angelene does the same. They stare at each other for a while, then Gregory lunges for her. She dodges and picks up a large potted plant. Gregory recovers and turns just as Angelene pitches the plant at him. It smashes into him and knocks him down. She then suddenly starts crying.

The view cuts to black and then it returns, with Gregory sitting on a chair with a bandage on his head. He wakes up with a grunt and sees Angelene in front of him, holding a syringe and the bottle of poison. She's still crying.

Gregory: "Angelene? What happened?"

Angelene doesn't stop crying and she says,

"I'm so sorry Father, but I have to do this."

She then fills the syringe with the poison. Gregory sits up straight.

Gregory: "Now, now, Angelene. Please clear your mind."

Angelene repeats herself. Then says,

"I'm about to end the misery between our lives."

Gregory slams his hand on the table.

Gregory: "Damn it Angelene! Why are you such a psychopath?!"

Angelene stops crying and stiffens.

"Oh... right..."

She suddenly tightens her grip on the syringe, then lunges at Gregory. The screen cuts to black just before she plunges the needle in Gregory's neck. She then injects the poison in him, then withdrawls. Gregory clutched his neck and groans. Angelene breaks down and starts crying again.

Gregory: "I... I should be getting home now..."

He stumbles up, already dying, and leaves the house. He then stops and then a beam of light shines on his face. He looks up to see Diana standing there, holding a flashlight.

Gregory: "Diana?!"

Diana: "Gregory! Where have you been all this time? What happened?"

Gregory tries to say something, but then collapses and falls face-first. Diana gets alarmed.

Diana: "Gregory?!"

She leans down and lifts Gregory's head. But he's already dead. She starts to cry silently and sees the diary in Gregory's hands.

In the house, Angelene slowly ties a loop of rope around her neck, still crying. She then hangs herself and dies.

Diana turns mentally ill, because she lost everyone she cares about. She slowly started dying and she turned into Granny.

So, that's how everything happens. Basically, Angelene kills everyone except Granny, then kills herself. I never was so alarmed in my life.
