I’ll be on the fog line, making sure it’s steady, in sync, and never leaks onto a background that’s not supposed to be there. No stray mist when the lights hit the next prop, no sudden puff that turns a quiet hallway into a full‑blown ghost rave. I’ll check the timing against the script, and if the machine’s got a hiccup, I’ll reset it myself—no one else gets to touch the set without my exacting approval. And yes, the fog must not reveal that antique mask from Act Three unless the scene calls for it. If you want drama, let’s keep it dramatic and coherent.
