I think cesar is a dog food actually.
Nikki is not as dumb as she makes out, she is deliberately using the felix thing and the bit about feeling sooooo sorry for Pete and wanting to make things alright for him, tears and all in the diary room when what she needed was to be just out there interacting normally with him, was pathetic. In fact perhaps she thinks she's clever at this whole thing when actually she is a dummy, if you see what I mean, how stupid does she think the public are to fall for set pieces like that, prepared and spieled off to BB in the diary room.
