He will greet Gorion's Ward and their party in Baldur's Gate Docks and inform them that Scar and Duke Eltan are trustworthy people in conflict with the Iron Throne. If your Reputation is 7 or less, he will think you too similar to your father, the Lord of Murder, and will attack you because of it. Killing him will further drop your Reputation.
