I think we can take it that the cook screaming is a hard move. So let's reason back - what player-side move failed, such that the cook was startled and screamed? The most obvious candidate is Act Under Fire.
So what was the character doing? Maybe they're the advance scout for the assault on Dremmer's compound:
First, let's imagine the player recites their PC's knowledge - it's a bit artificial as an example of play, but provides some context.
"I know that Dremmer has a storeroom at the edge of the compound, with a gate for taking deliveries. There's a fancy electronic lock on it, so it's not well guarded. I reckon I can crack that lock and sneak in."
The GM nods: "OK, so you're at the gate to the storeroom. It's locked like you expected. It's not well guarded, but that doesn't mean no one ever comes by here. You haven't got all night."
"OK, I bust out my tools and work on the lock, as quickly as I can."
"That Acting Under Fire, and the fire is - you'll be spotted before you're in." The player rolls, and succeeds on a 7 to 9. The GM offers an ugly choice: "You get it open, but you can hear someone's coming. And you can't see yet what's on the other side of the gate. Do you go through into whatever's there? Or wait to see who comes?"
The player decides to go in. "There's someone in there with a torch. Looks like Dremmer's cook Pattycakes, come to grab a fresh bag of chowder powder. What do you do?"
At this point the player has a few choices, but let's suppose that, whatever they do, it fails on a 6 or less. And so the GM narrates that Pattycakes spots them and screams.
I assume that DW could play out in a pretty similar sort of way.
