When future stops smiling at the end when Rabbit walks away
Rabbit declined his offer to host the shows with him. Future looks on and smiles, but then he stops and looks sad. He also takes a last look at rabbit when walking back
It’s like this is the moment where rabbit sort of drifts away and leaves future & the others. He won the battle, but his luck is changing. It kind of hints that he soared upwards and left in a hurry
