Keep drafting when a detail is missing
A visible placeholder can preserve momentum without allowing an unresolved detail to disappear.
Writing
Select one moment of pressure, then let action and response carry the information that summary currently supplies.

A summary can cover an entire difficult winter in a paragraph. A scene needs a more specific unit: a person, a place, an immediate situation and something that changes while we watch. Before expanding a passage, decide which moment deserves that closer attention. Turning every reported event into a scene can bury the important material beneath unnecessary performance.
Consider an invented summary: “During the winter, Ruth stopped trusting the caretaker because he repeatedly ignored repairs.” The history may be enough if it only explains Ruth's attitude in a later encounter. If the loss of trust is a central turning point, choose a particular repair request through which it becomes visible. Perhaps Ruth arrives with a leaking bucket while the caretaker is preparing the building for a visitors' tour.
That choice supplies competing immediate aims. Ruth wants the leak addressed before another room is damaged. The caretaker wants the tour to proceed without interruption. The scene can explore their conflict without reproducing every repair request from the previous months.
Begin close to the pressure. Ruth may have rehearsed a polite explanation, but the bucket drips onto the freshly cleaned floor before she can deliver it. An action like this establishes the physical situation and makes the problem difficult to ignore. The caretaker's response then gives Ruth something to interpret and answer.
Build the exchange through changes rather than through an equal distribution of speech and description. A promise of help might briefly reassure her. Discovering that the caretaker has recorded the repair as completed changes what she can reasonably believe. She may decide to photograph the damage rather than accept another verbal assurance. The scene ends with a different relationship and a new action available to her.
Keep the viewpoint close enough to make the experience legible. If Ruth is the viewpoint character, we can see the caretaker straighten a display and hear his explanation. We cannot state his private motives as fact unless the narrative has established access to them. Ruth's suspicion can be powerful precisely because she must act without complete knowledge.
A successful expansion still leaves things out. The three earlier requests, the plumbing's installation history and the whole tour schedule may require only a sentence or two. Insert such context when it changes the meaning of what is happening. A detail introduced just as Ruth recognises the supposedly completed work will usually have more force than a preliminary dossier.
Read the new scene beside the surrounding chapter. Does the reader now experience a consequential decision, or merely learn the same information at greater length? If nothing is gained by watching the exchange unfold, summary may remain the better choice.
You can also combine the two forms. Summarise the repeated disappointments, dramatise the decisive encounter and return to summary for its routine aftermath. The purpose of the scene is to concentrate attention where the reader needs to feel the pressure of a particular moment.
