You enter a blue brick building and approach Sword, who is dressed in a somewhat... futuristic style? What gives with this new outfit change?

"Greetings from the future. I'm not meant to be here, I'm hiding for now." he says, which suggests that you have encountered a Sword from the future who has come to the present for unknown reasons. His suspicious and stealthy manner implies that he is keeping a low profile and trying to avoid being spotted by others.
