You're a safe class SCP and you're allowed to roam the halls of Site-19. You have a standard humanoid safe-class cell decorated to your own desire with personalised items and your own level-1 keycard for the site.

You're walking down the hall heading to the cafeteria some guards give you friendly waves as you pass. You start to hear commotion as you get closer to the cafeteria, curious you walk faster and reach the cafeteria.

Everyone is gathered around two guards who are fighting one smaller guard is being punched in the face over and over by a taller guard. You also don't know how it even started.
