She does it a couple of times I think - I remember the gloating at the start of the series and then again with the amnesia (brilliant storyline). I wonder if Vera really gets how the women feel towards her? When she is training the new officer (Debra Lawrence - can't remember the screen name) Vera doesn't seem to get that the women have no respect for her at all. It took me a bit of watching the show before I got the idea that she didn't bait the prisoners in front of the other officers.
