Add details, answer questions, clarify the scene

Flesh out the scene as much as you need to, in response to player questions or PC actions. Draw a quick map or picture if you think it will help. Figure out who's where and doing what. If there's confusion or disagreement about what's going on, try to get everyone on the same page.

Make a soft GM move If you zoomed in on this place solely because it's a landmark that hasn't been seen on screen before, and you don't really have anything else to do here, then just offer them an opportunity. "Okay, does anyone want to have a conversation incharacter? Or do something else here? Or do you move on?"

Otherwise, make a soft GM move. Say something that provokes the PCs to act and/or that increases tension. Your exploration moves (next page) will be particularly useful here.
