User blog comment:CenturyKiller/Does anyone believe Matriarch Aethyta could be Liaras she-father?/@comment-69.122.240.63-20120216012621

the picture Aethyta is holding is identical to the one Shepard would have in his/her room if in a relationship with Liara. It is very possible that Aethyta is the paternal parent. But as long as Bioware does not confirm it, it is not considered fact.
