Object Class: Euclid
Containment Procedure: Luckily, as long as the SCPs are contained together, they do need need special security measures. They're currently being contained in a simple cell with an iron door. There is observation and supervision deck to allow access. The main cell has a low security lock that can be reached in the O&S deck.
Description: Scp-5483a is a slim, approximately teenage girl, with pale skin and dark eyes with dark hair, often tied behind her head in a pony tail. She is always silent when alone with 5843b, aside for soft, windlike exhalations. When there is a person in proximity to them, she will always walk up to them in a suggestive manner and begin whispering to the person who enters the area. The person, if they survive the encounter, will almost always refuse to repeat what she whispered to them. Any who attempt to will immediately commit suicide in the most accessible manner, whether it be snapping or slitting their own throat, or with any reachable weapons.
Scp-5483b is a boy, around the same age as 5483a. He has pale skin but completely white eyes. It is unknown whether he is blind as he follows the movement of his female counterpart but remains unresponsive to any other outside visual stimulus. He is constantly muttering to himself in rhyme and if anyone enters proximity, he will attempt conversation with them but still in rhyme. It has been discovered that they must speak to him in rhyme also or he will stand up, scream and attack them, killing them violently and with unusual precision. Then both the the girl and the boy will dismember the corpse and pile it, organ by organ, body part by body part, with no direct organization. It has been discovered that if the subject who enters the proximity makes contact with 5843a, she will scream and curl up like a small child, as though she is in agonizing pain. 5483b will then proceed to kill and dismember the subject. He will then comfort the girl and they will continue as if nothing happened.
Also, if they are separated and contained within different units, they stand up and face where the other is contained, 5483b will sing softly and look sad. 5483a will scream and hit the wall of her container with her fists until they're reunited.
