in a mission called farewell my love when the cops throw u in the country catilina is in love with someone else it it resembles the guy from gta 3 but i was just pointing that out..i dont think she ever said his name.. and 1 other important thing...Catilina when u beat the mission she gives you a deed instead of his car cuz they have to go to liberty city..and then carl looks at him weird and says liberty city..and it kinda does a close up on him..so im guessing it is him.
