Or lack thereof, clicking talk does nothing so you cannot progress that questline at all without other drastic measures.
Still some pretty glaring issues with story progression in the game, rescue Halsin and he just disappears so gone entirely from the game, closes off all related questlines through Act 1, 2 and 3 with what amounts to a shrug in the description.
Love the game and all the work Larian is doing, but some of these questlines are core to the game around significant characters.
