It happened in another universe:An SCP universe that is.It was a cleaning day and there were 3 d-bois.One was keeping it’s eyes on 173 while the other was on the other 173.173 duplicated while they were looking!”Your facing the wrong way”one said.The other:”No,your facing the wrong way.”The first one:”What are you looking at?”The other:”173,what are you looking at?”The first D-class didn’t respond.173 was in both of their sights…until The Who told him he was looking at 173 sneezed.Then he was dead.Before the first had time to turn around he was killed by an SCP 173.The one on cleaning duty was able to keep them in his sights until they were recontained in separate cells.But still they were able to duplicate and had a hive mind.They kept on breaching containment.They were classified Keter.Then they were to be transported to the lunar surface using SCP-120.But even they were able to cause death throughout North America.They then had the whole foundation (That was in North America) go to the other side of the world (Europe) But still,the 173s were able to cross water.They nuked North America/The Americas and soon The UK.They were never stopped.But on the bright side:They all together (About 120-150) killed 682!See,Even if 173 is in your line of sight,You are dead from it’s clone.The line of sight is when 173 duplicated.Don’t blink to 173 or it’s clones!
