Neon Genesis Evangelion What did he say?

In EoE right before *SPOILERS SPOILERS SPOILERS* Gendo shoot Ritsuko he says something and then Ritsuko says, "You liar." Any guesses on what he said. I know it may be nothing at all and Anno was just pissed off and didn't care what people thought anymore but *shrugs* what do you think he said.

 

Either it was some kind of Animation\script error (acidental or purposely) and nothing was supposed to be said there OR he said "Your Worthless" or something like that...
