Using current observational data and simple dynamical modeling, wedemonstrate that Omega Cen is not special among the Galactic globular clustersin its ability to produce and retain the heavy elements dispersed in the AGBphase of stellar evolution. The multiple stellar populations observed in OmegaCen cannot be explained if it had formed as an isolated star cluster. Theformation within a progenitor galaxy of the Milky Way is more likely, althoughthe unique properties of Omega Cen still remain a mystery.Comment: published version with minor change
