The thing that bothers me is that... what happens to the things that turned into something due to the paramecia awakening after they are transformed into that element? We've seen Doflamingo turning buildings into strings and while he was walking, the floor turned into a pile of strings but reverts to normal after he stepped away from it. The floor returned back to its original form but what happened to the buildings that have been transformed? Did they returned to their original state as pieces of stones? What do you guys think? (Same goes for Katakuri's DF)
