I once deleted system32…That’s when I began calling the shots.

I didn’t see them actually say what was mixed with bleach, but can assure it’s ammonia. Although if that is the case, the chlorine gas that is (somewhat) generated reacts with various amines present to create chloramine gas.

Chloramine gas is what people die from when mixing bleach and ammonia. Chlorine gas will also kill you, but in these cases it’s chloramine gas.
