While I still curious who "she" is, but if both side are consistent, I would believe that it actually a vessel for Shinjuku Grail, but because the vessel would be the "Fallen Lord"...so, it can't be. At first, I believe that Lancer talk to Saber and Alter Ego, but Alter Ego can't join right now because she isn't awake yet.

I just start to think that those sentence could belong to "Alter Ego of Time" or at least, her "embryo" or "origin form" (whatever it called) before she could reveal her true form in "DI IV - Orleans", as they trying to awake her, but failed.
