No...the secret room person does not leave BB and give interviews etc...so cant be PM...though she was a good candidate for this !!!
Nope she is too dumb to use it to her advantage. She is more caught up with her petty issues and jealousies. Sky and the guys can talk whatever rot they want about her, she will still blame the girls.
Also she didn't play it smart during her stint as a captain. If she felt Sid was misbehaving she could have easily sent him to jail or waited for nomination day to nominate him but instead she did what she did, then lied about it and now goes around portraying herself as some victim of the evil house (like Sky did). I think BB made the right decision kicking her out, her action with the broomstick was clearly violent and uncalled for as were many other such instances where she behaved extremely unreasonably. This was the last straw and was again uncalled for.
