80% Possibility

Someone is calling you, Raya. What? Oh, I will answer it right now. Fine, I am going down to eat. Yeah, go on. (Raya answers the call.) Jakijo, is that you? Yes, Raya, it's me. So, about the information you wanted, I have some good stuff for you. Well, based on what I found, both of them seem to be siblings. (When Raya hears this, she screams, "WHAT!!!") How did you do that, Jakijo? Are you sure?! Let's say 80% possibility. At first, when I searched about them, I could only find that Rion was a teenage boy interested in coding. I couldn't find anything about Rin. However, when I did some hacking, I found documents indicating they were siblings. More than that, I tried a virtual DNA analysis based on their appearances, and it showed they are likely siblings. That's all for now, I will inform you if I find more. (Jakijo ends the call.)

(Raya falls to the ground and thinks, "Should I tell them? But if they aren't, then I will have suspicions even against Slen.") (Raya goes down to eat.) (She sees Rin feeding Rion since he can't use his right hand due to an injury.) (Raya blushes.) Stop it, I will do it. (Raya grabs the spoon and gives Rion multiple spoonfuls of food, almost causing him to choke.) Finally, I don't have to deal with feeding him like a baby. It's okay, Rin, I will do it for you. (Raya says while keeping in mind that Rion and Rin might be siblings.) Rion choking is heard. "Are you alright?" says Rin as she moves to give him water. (Raya stops her hand from touching Rion.) I can give it to him, Rin. ("I have to spill the beans or else my mind will explode.") (Wait, Jakijo said there was only an 80% chance, so that means the 20% still exists. To be 100% sure, I will make them do a DNA test.)

So guys, I need both of you to give me a strand of hair to add to my collection of best friends. You know, it's like a habit of mine. (Rin tilts her head and says,) Are you a psycho? No, it's just a habit of mine. (Raya anxiously says.) (Rion looks Raya straight in the eye and says,) You sure you don't want to use them for a DNA test? (Did he hear me before? Keep calm, Raya.) What? Of course not, Rion, why would I do that? Don't know, people only take hair for DNA tests. (Rion grabs a knife, cuts a strand of hair, and gives it to Raya.) Here you go, crazy girl. So, Rin, would you give me your strand of hair too? Don't even think that will happen. (This girl is unbelievable, just give me the strand of hair so I can test if you are brother and sister or not, Raya thinks in her head.)

(A strand of hair is on Raya's leg.) (Raya puts her head close to Rin's legs, sniffs at them, and then licks her leg with her tongue.) You psycho bitch! (Rin kicks Raya away.) (Yep, there is no mistake, they must be brother and sister. Even the pain they give me is the same. But still, now I got Rin's hair on my tongue. It's just a matter of time now before I discover the truth about what is happening here.)
