Potioncat:
Hmmm. I think you're right, for two reasons that came to mind after I 
sent the post. LV wouldn't send Lucius into the battle to get Snape 
that's what Lucius wants to do so that he can look for Draco. If 
Snape had been in the battle, he would have been looking for Harry, 
and we would need to see some hint of it. That is, for his being 
there to have any meaning. So his request to "return" to the battle 
means that he left the battle when he fled the Heads. I was thinking 
the battle started later, but that's really the moment it started.

So, Snape must have some assignment that gives him some overview of 
the battle. Some fancy Aide de Camp or something. (I have no idea 
what an aide de camp is, or how it's spelled.)

But I don't think he knew about Nagini's protecion until we see him 
in the Shrieking Shack.
