In the mission Citadel: Volus Ambassador the outcome depends, in part, on whether Zaeed Massani survived the events of ME2 and if he was loyal.
It's not entirely clear from this answerthis answer whether he will be present or not as I don't know if his missions were from DLC or N7 missions, having not played the other titles.
Did he survive and was he loyal if I don't import a saved game?
