casual remark

That tip of the hat was no casual remark.

Yet another benefit was born of a casual remark from the boss.

Mr. Biden made the oddly casual remark about a potential deadly disease in a speech about global warming, citing emissions from oil refineries near his boyhood home in Claymont, Delaware.

Every gesture and every casual remark that must be repeated to see one of the possible endings acquires a different sort of gravity.

That said, while a casual remark leads to a big reveal, it is hard not to scoff as several leads drop almost effortlessly into his lap.
