Tight coupling between synaptic vesicle exocytosis and endocytosis is critical for the maintenance of neurotransmission. In this issue of Neuron, Zhu et al. reveal a surprising facet of this coupling by showing that, at low frequencies, fusion of a single vesicle leads to retrieval of two vesicles with dissimilar attributes.
