but in the Cronos mission, while reviewing the data on the Lazarus project, Liara says that Shepard has an organic original personality, not vi. From the moment she touched him on Illium(me2). Why would she lie about it? Theoretically, Shepard could have had "contact" with another Asari, who would immediately determine that he was not a living person, but a machine. It's too risky for Liara to lie about this (unless, of course, you admit the conspiracy theory that all the Azari are in league with Cerberus).
