I still think it was Perry. He seems to have disappeared about a month ago, unless I'm reading the posts wrong. That's just enough time to plan his re-entry, make up a story, change genders, try to get everyone on his side initially. Nicola also didn't flinch when I called her/him Perry. No response at all, which I think is odd for a newbie with no agenda.
He tended to ignore my comments the very few times i entered his OPs and always directed his responses/angst towards others, such as Viv. We saw the same thing in this OP; most of us were more or less invisible once Viv came on the scene. I think he has become completely unraveled just like the picture posted by Village Idiot above.
