Y/n heads to Tai's house. Y/n sneaks inside and hides in a corner. The dim light in that corner with his dark clothes should hide him.

Y/n watches Tai walk down the stairs and soon after Ruby enters.

Ruby: Dad!

Tai: Hey Rubes. I've been expecting you.

Ruby: I know.

Tai: I know things too. Like why you are here.

Ruby looks around for a minute.

Ruby: Dad...are you...really my dad?

Tai sighs.

Tai: No. And there is no point in me lying to you about it. You already know the truth, from what Ozpin told me.

Ruby: Then, is Y/n L/n my dad?

Tai: Why don't you ask him yourself. I know that you are there, Y/n.

Y/n steps out of the shadows, surprising Ruby.

Y/n: You knew?

Tai: Oh please. Spend years playing the same game of spot the Y/n, you get good at it.

Y/n: I...see.

Ruby approaches Y/n. Y/n looks away from her in shame.

Ruby: You...are my dad?

Y/n looks at her.

Y/n: I'm sorry. I asked Tai to look after you for me. I...couldn't.

Tai: Well, she made it this far. Might as well not leave anything out.

Y/n nods.

Y/n: Ruby, you and I share blood. But the part that makes you a vampire, lays dormant. It was a blessing, to keep you from being hunted for what you are.

Ruby: I...see.

Ruby looks at the ground.

Ruby: Was...mom a vampire too?

Y/n: No. She wasn't. She was a human.

Ruby: Will you answer all my questions?

Y/n: I will. The time for lies has ended. Come, walk with me.

Ruby: Don't vampire's hate the sun?

Y/n: Most do. But some can still walk in it.

Y/n and Ruby walk outside and walk into the woods.

Y/n: The world as you know it will be shattered. There are many creatures that are not myths.

Ruby: So. If I am a vampire, why don't I need to drink blood?

Y/n: My theory is that the vampirism is locked inside of you. It is probably unlocked by the consumption of blood.

Ruby: That sounds easy enough.

Y/n: To avoid. Which you will do, at all costs. I know about the cave, Ruby.

Ruby: Oh. Well then what do you think the other one was?

Y/n: The one with silver clothes?

Ruby: And the glowing eyes.

Y/n: I don't know. That would be whatever gift you got from your mother. Probably you unlocking her abilities, not mine.

Ruby: But couldn't I just do both?

Y/n: That...I do not know. However, do not ask to be a vampire. You will find that road lonely.

Ruby: You seem to be okay.

Y/n: I wasn't always okay. You have been my reason to live all these years.

Ruby: So...what did you do before all this then? How did you survive?

Y/n: Like any other. I fed on blood. I limited myself to only those that choose to do bad things to others. That was before the substitutes, when vampires were driven into even more seclusion than before.

Ruby: Did you cause that?

Y/n: Yes, I am to blame.

Ruby: That must've been hard for you, right?

Y/n: You think I feel bad?

Ruby: Maybe?

Y/n: No. I don't. Vampires are horrible monsters that feel no empathy for their actions. Born with hatred and narcissism in their hearts, from the minute they get their curse!

Ruby: Then what happened to you? Why do you, hate them? Did they...kill mom?

Y/n: No. I do not know who exactly killed Summer. If I did, I would've already taken their head.

Ruby: Did they kill someone else then?

Y/n: Yes. A very long time ago, before even your great grandparents were born. Probably a millennia or two ago.

The two make it to a hill overlooking a lish field.

Y/n: I've come to appreciate the beauty of nature. The trees, the grass, even the animals that call it home.

Y/n sits down and Ruby joins him.

Y/n: You really want to know?

Ruby: Yeah.

Y/n: I used to know a child, a kind soul that never sought harm to anything. At the time it was a very rare thing. He took great care for even the smallest bug. However at the time I had some allies who weren't fond of humans.

Ruby: I'm guessing that started a problem?

Y/n: Yes.

Y/n looks at his hands.

Y/n: I stopped caring for humanity for so long, I forgot what it was like. Until that little boy reminded me of how it is to be human.
