A lot of characters and encounters that take place during Act 1 of Baldur's Gate 3 can resurface much later in the game. One such person is Oskar Fevras, the subject of the side quest "Free the Artist." Players who help him out when they find him can meet up with him again once Act 3 begins and players have full access to the Lower City of Baldur's Gate.
