He's the leader and gives you multiple quests. 3.Accept the interrogation quest, and go meet the lady upstairs to start the quest. 4.When you get in the room to talk to Sirus, pick the Intelligence Option first, followed by the Speech option, followed by the Intelligence (8) option. Any of the 3 Intelligence (8) options work. 5.After that, hit the Speech option (which should now be grayed out) and cycle through the Intelligence (8) options more. You will gain 50 exp every time you cycle through the options.
