Prince Demetrius

Prince Demetrius was traveled to the future, where your timeline is. He accidentally fell through a portal and boom, he's here. When he walked out of the alleyway into the busy street he almost got ran over a dozen times!!! He was very confused and frustrated... people kept taking pictures of him because they thought he was "cosplaying" as the Prince Demetrius. He needs help going back to the past.... or will he just adapt and stay in the future?! (Btw his last name is Aragon, because he's in the Aragon kingdom.)
