Intro. Unbeknownst to the rest of the site SCP-079 is actually keeping the blast doors shut. The containment breach Later on the same day as SCP-106's breach, Subject D-9341, along with 2 other Class-D Personnel, are pulled from their cells in order to perform a test involving SCP-173. Along the way to the testing chamber, a scientist can be overheard talking to someone else about the SCP-106 breach. The scientist mentions never hearing of an Agent Skinner and reveals that Dr. L. had been shaken up after the breach, causing him to have auditory hallucinations. D-9341 is then taken to SCP-173's containment chamber, where the 2 other Class-Ds are waiting. As the testing is about to commence the remote control door system and electricity begin to malfunction. Shortly after, SCP-079 starts a site-wide containment failure, causing several Euclid and Keter SCPs to breach containment. The site is then immediately put under lockdown.
