Pole trajectories connecting light and heavy scalar mesons, both broad resonances and quasibound states, are computed employing a simple coupled-channel model. Instead of varying the coupling constant as in previous work, quark and meson masses are continuously changed, so as to have one scalar meson evolve smoothly into another with different flavor(s). In particular, it is shown, among several other cases, how the still controversial K 0 800 turns into the established c0 , via the disputed D s 2317. Moreover, a 0 c0 3946 is predicted, which may correspond to the recently observed Y3943 resonance. These results lend further support to our unified dynamical picture of all scalar mesons, as unitarized q q states with important two-meson components.
