At the market, you will meet Reginald, who is entertaining the crowds by showing the talking head. After you have investigated in to the matter, by talking to Gallagher, who is cheering the crowds nearby, you will learn that Reginald paid him to do that job.
Now, go to the opposite side of the square, where you see Cedric, who has no spectators. Inform him that Reginald paid Gallagher for the fake crowds and he will ask you to bribe him.
During the conversation, use your best attribute to convince him, to change sides. If you succeed, Gallagher will work for Cedric.
Return to Reginald and tell him that his employee is now working for the competition. He will not take kindly to that and the quest will end.
