SCP-2428-1: I just sort of… was, one day. Some of the others said they felt weird, like their brains weren't quite hooked in right. Sometimes Doctor would have a look at them, off in his workroom or whatever, and they'd come back a little different. Talk different, look different. Sweetie changed more than that, I remember. But I think the old me— provided there even is an old me— was still pretty much there. Here. Whatever.

Dr. Segerstrom: So you think you had a life prior to becoming a Wondertainment product?

SCP-2428-1: I think so. Hell if I know what it was, though. I just seemed to have a more… I guess you could call it "stable" mental state. Which is funny, if you think about it. The others all had their little quirks to go with their theme, but I was just… the imaginary guy. I mean sure I looked the part but I didn't feel particularly mad. I guess those who are don't, though.

Dr. Segerstrom: Do you think there may have been a reason for that?

SCP-2428-1: I saw some stuff when I was around Forgetful. The others seemed to have some kind of reason for being, you know? They had a purpose. I get the feeling Wondertainment made me like this just to see if he could. It doesn't help I was never really around much, I think I was "awake" for all of an hour a couple years ago.

Dr. Segerstrom: And how do you feel, following that logic?

SCP-2428-1: Shitty, I guess. Like I was made and discarded. Then I wonder if I'm being paranoid. But I can't shake this sense of… dependency. Like, my very existence is entirely dependent on your mind being abnormal, and perceiving me. But what if I don't entirely transfer over? What if I'm just a sort of reflection of the owner, in a way? Built from their mind? So now I question how real "I" even am, as unreal as I obviously am.

Dr. Segerstrom: We've done blind tests on that, Mad. We know your memories carry over regardless of what the owner knows.

SCP-2428-1: But that doesn't disprove I'm being altered by the owner! Sure, I might have the same memories, but am I still the same person?

Dr. Segerstrom: Those that read the transcripts will note any inconsistencies, but that would require extensive testing across subjects— or owners, rather. So, do you think you're not sapient? If I were to have other hallucinations, would you be subject to them or simply aware of them?

SCP-2428-1: I mean, I wouldn't know the difference for either question. Your hallucinations are no more or less real than this table to me, which you could be hallucinating. And to check whether you are, we could have another person try to interact with it. But then maybe they're also a hallucination. Which, from my perspective, still doesn't make any immediate difference. You're the only concretely "real" thing. Regardless of how reliable you are cognitively, I'm only here because of you.

Dr. Segerstrom: So now what?

SCP-2428-1: I don't know. I guess there's no real way to know without testing it.

Dr. Segerstrom: Would you like to test it?

SCP-2428-1: I guess so. I haven't really put a whole lot of thought into it before, what I am or what I want. But I guess I can't help what I am. And I think I want to try to leave a mark, somehow. Might as well try to help those I know are real. If I can remember to do that next time.
