.......what the actual fuck did I just look at? I don't really follow SCP, came here from all. I'm lost and afraid... please explain what is happening!
Edit: to be clear, I am aware of SCP, and kinda understand what it's about. I am open to not just an explanation of this comic but a broad explanation of SCP in general.
The stuff happening in some SCP entries make the same sense that Joan Cornella's art and comics. I don't know if some specific entry is related to this comic, but here's the original
In the SCP universe, D-Class personnel (prisoners in orange suits) are essentially cannon fodder for anomalies. The comic joke is basically the extreme reaction where the guard "saves" the D-Class from SCP-173's neck-breaking grab by shooting him.
That SCP only moves when you aren't looking at it. Think Doctor Who's Weeping Angels. I'm guessing the researcher called to help the man. The guard figured he would save the D-class by shooting him himself.
