In this article, I analyze patterns of reflexes of Ā-movement found within and across languages: reflexes may occur in all or none of the clauses of the dependency, in the clause where the dependency terminates, or solely in clauses where it does not terminate. I argue that the variation can best be captured by the variable timing of Agree and two subtypes of internal Merge (final vs. intermediate movement steps) triggered by a single head: early movement feeds Agree and gives rise to a reflex; late movement has the opposite effect. Since the subtypes of movement can apply at different points relative to Agree, reflexes may occur only in some clauses of the dependency.
