And while appearing without being detected by the residents, Gold is stunned to see Belle and Will embrace a kiss. Back in the Enchanted Forest during the first curse, Snow White & Prince Charming are asked by the Queens to find the Tree of Wisdom so they can get the answers on how to stop Evil Queen's curse.
