… A TIME

This phrase completes a common saying about patience being a virtue—think of what follows "all in good" to form the full idiom.

This clue is part of a "split answer" where the full phrase is divided between two clues. The answer here is the second half of a common expression—when combined with 31-Across (likely "ONE"), it forms "ONE A TIME," a play on "one at a time." The ellipsis at the start signals it’s a continuation, and the phrasing hints at the familiar saying about doing things sequentially.
