The description of the grappled condition reads, in part:
The condition also ends if an effect removes the grappled creature from the reach of the grappler or grappling effect, such as when a creature is hurled away by the thunderwave spell.
For the grappled condition to end, does the grappled creature have to be the one that is moved, or can the grappling creature be the one that is moved?
For example, could a College of Swords bard's Mobile Flourish* be used to push the grappling creature away, ending the grapple? Or would the bard have to attack the grappled creature with the Mobile Flourish in order to end the grapple in this way?
