Ichigo has consistently proved to be OP, and now I have a strong belief that when his swords were done, they were actually fire element. Maybe the whole blacksmithing thing was for effect, or maybe they're fire element and melt the whole lake or whatever. And also, isn't Isshin's bankai fire-based as well?
Soul Society seems to be pretty cool with Captain-class people just up and disappearing and then coming back to help..
