How about a story where Rainbow Dash accidentally discovers a hidden talent that Sombra has for art? She then encourages him to show his work to the rest of Equestria, but Sombra is shy and hesitant. Rainbow Dash has to use her confidence and charm to convince him, and in the process, they become good friends and inspire other ponies to explore their hidden talents too.
