User blog comment:CenturyKiller/Does anyone believe Matriarch Aethyta could be Liaras she-father?/@comment-2256917-20100926030933/@comment-3086499-20100926235701

It is possible. Most people that don't think it's possible are thinking in terms of being in the mass effect universe themselves. Think meta-game. This asari conveniently happens to be a matriarch, mentions that she had a pure blood mate and that it didn't work out, and indirectly makes mention of benezia.

Not to go too off topic, but this isn't the only time where bioware gives these little hints and clues about characters throughout the game. For instance, Aria on Omega mentions that the "patriarch" isn't the only krogan she's pissed off, She mentions that she had commando training and that she was a merc, changed her name, and then at the end of one of her conversation strings bioware makes a point of her saying "better luck next time". These little clues might be missed if you don't pay attention, but it all points to Aria being Aleena from Wrex's story in ME1.

My point is that that you shouldn't rule the asari bartender out due to being cultivated by the immersion of the game. Instead, take notice of these little clues.
