I noticed when Lois referred to "Luthor". That has to be the true moment of victory.
True, the way she had looked at him, and her managing to get in there at Star Labs were already good signs.
I understand why Clark is so afraid. The place does sound like a prison. It also seems to not have been chosen as the optimal place for him to recover. On the other hand, I guess since they were cutting out the Krptonite, this may not have been the recovery place.
I was just so impressed that Lois said "Luthor" that I had to comment on it.
