 Item number SCP-2151 Object Class Safe Special Containment Procedures SCP-2151-A and SCP-2151-B are to be kept in separate high-security containment lockers of Site-81. Testing of SCP-2151-A and B is currently suspended. SCP-2151-A1 is to be maintained at Site-81 indefinitely, or until SCP-2151-A1 expires. Description SCP-2151-A and SCP-2151-B are nearly identical stainless steel rings. Aside from their effect on human wearers, they present no other anomalous properties. The two human beings wear SCP-2151-A and SCP-2151-B. Any physical contact between them will activate SCP-2151-A and B. Immediately upon contact, the two instances will increase dramatically in temperature and burn into the skin of the wearer. This happens quickly, and typically takes less than 20 seconds before the objects disappear under the skin of the wearer. The point of contact between the two subjects will also increase in temperature, often resulting in severe burning in the area, and the skin there will fuse. As time passes, more and more of the skin connected to two individuals will become fused, eventually consuming the entire bodies of both subjects. Over time, the distinguishing characteristics of the individual subjects will become distorted and unrecognizable from their original state, and many of the biological functions of the individuals will shut down entirely. Similarity in this process to the creation of instances of SCP-427-1 has been noted. The potential of a similar origin for SCP-2151-A and B and SCP-427 is currently under investigation. The resulting entity is classified as SCP-2151-1-X. It is currently uncertain whether any higher mental functions are maintained throughout this process. At the end of this process, SCP-2151-A and SCP-2151-B will be pushed out of the resulting body by seemingly natural processes. No other anomalous activity occurs past this point. SCP-2151-A-1 is an entity believed to be the product of SCP-2151-A and SCP-2151-B's effects on two human beings. This entity was discovered at the home of Mr. ██████ and ██████ in the room of ██████-C Addendum 2151-A for more information. Despite additional instances of SCP-2151-1-X expiring shortly after formation, SCP-2151-A-1 has persisted for more than 30 years since discovery. Research into how this is possible is ongoing. Addendum 2151-A Discovery SCP-2151-A, B, and A-1 were initially discovered in the home of Mr. ██████ and ██████ in the second floor room of their youngest daughter, Monica. Current SCP-2151 timelines have revealed that the initial contact event began on 17 September 1971, at roughly 1900 hours, when Mr. ██████ were away from the home. Upon discovery of the SCP-2151-A-1 entity, Mr. ██████ alerted the local authorities and Foundation agents intervened. Amnestics were applied to the family and cover story P-315-B, fatal car accident, was spread through the local community. It is currently believed that Monica was wearing SCP-2151-B at the time of contact due to genetic material belonging to her that was recovered from the object. The other individual has not yet been identified, although genetic material collected from SCP-2151-A-1 has shown that the subject was likely approximately 50 years of age and shared at least ████ percent of their genetic material with Monica ████. Addendum 21-51-B, Note Transcript The following note was discovered on the back of a photograph of Monica located in a waste bin in her bedroom. The origin of the image and the author of the note are both undetermined. My sweet Monica, I know you can never see us like I see us, but I know we are meant to be together forever. I think you'll agree with me after tonight. You are so beautiful. I love you.
