I'm still betting the Shadow Broker is, or knows something about, Liara's "father". Mass Effect enjoys giving players the option to choose between good and evil, and I'm betting this DLC will have a choice at the end.
The Shadow Broker is up against a wall, so he pulls out a trump card on Liara: Spare me, and I'll tell you about your father. Liara already lost her mother, and this would probably floor her. However, she's spent the past two years thirsting for revenge. Unable to decide what to do, she turns to you for help.
Good option: Convince her to spare S.B., as they can probably find him again, but this is the only chance Liara will get to know her "father".
Bad option: Kill S.B. Liara gets revenge, but looses her chance at knowing her family.
Or I could be completely wrong. Still, BioWare threw in that line in Mass Effect that Liara never knew her "father", and I just can't let that go (BioWare doesn't throw in useless stuff). Who better to have knowledge of a long lost relative than someone who's entire life is based on info?
