The single-particle excitations, which initiate the pseudogap in the cuprate superconductors at some temperature T^*, relate to specific local spectral features of resonant pairing, where charge carriers get momentarily trapped on dynamically deformable molecular Cu-O-Cu clusters. We show how those local excitations evolve into dispersive branches with a characteristic "S"-like shape for three-peak structured ingap excitations in the cuprates' pseudogap phase, when we consider a lattice of such clusters. This feature should be detectable in "momentum distribution curve" ARPES analysis.
