Doffy: "I'll show you. My "awakening!" Doflamingo's strings "awaken." The surrounding people turn into strings (?) and attack Luffy Luffy: "No way that's really a paramecia power" Doffy: "Devil Fruit powers can be 'awakened.' But you're nowhere near that level"
The townspeople lose the will to run from the strings (?). The king or mayor or somebody says "Strawhat Luffy's still fighting, so don't give up!" The townspeople are encouraged. Luffy hits Doflamingo with Lion Bazooka. End.
Last, Luffy said (to Doffy) 'Time's almost up, I'm gonna send you away with one blow. This is the last. Gomu Gomu no Lion Bazooka!' It could be that Luffy was talking about the birdcage is shrinking, so no time left, he must hurry and defeat Doffy.
