Addendum-12141-A: Dialog between Maria Explonang and Dr. Vandra
Dr. Vandra: Good morning, Maria. How are you feeling today?
Maria: I'm feeling fine, thank you, Doctor.
Dr. Vandra: I wanted to talk to you about the incident that happened in your bedroom the other day. Can you tell me what happened?
Maria: Well, I woke up and saw a skull on my nightstand. At first, I thought it was just a weird dream, but it was real. I freaked out and took a few pictures with my phone.
Dr. Vandra: Can you show me the pictures?
Maria: Sure, here they are. (Maria shows Dr. Vandra three pictures on her phone)
Dr. Vandra: Hmm. That first picture looks like it could be SCP-12141. Do you remember anything unusual happening after you took the pictures?
Maria: No, nothing really. I mean, I felt a little weird, but I figured it was just because of the skull.
Dr. Vandra: I see. Well, I have to tell you, Maria, that SCP-12141 is a highly dangerous object. It has been known to cause hallucinations and violent behavior in people who look at it.
Maria: What? But I'm fine! I haven't done anything weird or violent!
Dr. Vandra: I know, but it's possible that the effects of SCP-12141 are slow-acting. We need to monitor you closely for any changes in your behavior or mood.
Maria: Okay, I understand. But why did I get a skull in my bedroom? Who put it there?
Dr. Vandra: We're not sure, but it's possible that someone is trying to use SCP-12141 to cause harm. We'll investigate further and keep you updated.
Shortly after the conversation, Maria died due to unknown causes. It is believed that her death may have been related to SCP-12141. Further investigation is ongoing.
