If Pathfinder Ryder chooses to abandon salarian Pathfinder Zevin Raeka to save a group of krogan scouts, Raeka dies and Lumont becomes the new salarian Pathfinder. During a gathering of the Pathfinders in the Nexus, Pathfinder Hayjer will reveal to his colleagues that he has been investigating the kett's Exaltation process in order to find a way to prevent it.
After the battle, Ryder can support Hayjer as interim ambassador to the Nexus.
Alternatively, if Ryder chose to rescue Raeka over the krogan scouts, Raeka begins training Hayjer as her successor. Later, during the battle for Meridian, Hayjer leads a squad of salarians in place of the krogan scouts.
