BB-8 rolled his way into our hearts from the moment we first saw him, managing the impressive task of recreating what audiences loved so much about his astromech predecessor, R2-D2. The little droid was a key part of The Force Awakens' plot, acting as the custodian of the map to Luke Skywalker's location on Ahch-To. Now that he's succeeded in delivering that, you may worry that he won't have much to do in The Last Jedi.
