I think so too. I worked alongside an absolute narc who got fired after spending an entire shift abusing my colleague cos he felt she had slighted him. He was told he wasn't to be on site while we were until the incident had been reviewed, so of course he made a huge production of leaving site late at change-over time or staying late and we were told to just ignore him.I'm firmly of the opinion, and I think @gigilouxx will agree with me, that deep down these narcs do know the truth, but they construct a new truth for themselves and absolutely believe it. So I think she's being 'truthful' when she can't recall/denies everything, but only in respect of her construction of truth, not the objective reality.
When he was fired not even a week later my colleague told me he had come in earlier that day to hand his access cards and laptop in (he had been told to do that at head office) and told everyone he saw that he had found a new job and that's why he was leaving so suddenly. Couldn't bear to not be in control even after being fired.
She strikes me as the same, I feel like her ego is so fragile that she's shitting out these ridiculous lies and contradictions and throwing everyone under the bus because she can't stand not being in control, and either doesn't realise or doesn't care that it's making her look guilty as duck. Her legal team must bleeping ate her.
