Harry is playing the victim
Not to the rest of the house but to us the viewers but she's completely misjudged it
She's trying to make nick feel guilty because he wants to talk to other people in the house
Then she sits away from the rest of the group and try's to make it look like nick has alienated from the group because he's kept her to himself
She hasn't taken into account what bb show either ,nick is the one being portrayed as the victim and Harry's true self is being portrayed as the bunny boiler she is

Harry isn't playing anything, what you see is what you get with her.

To be honest I really don't think she knows how to playing the game. She is the only HM who knows she won't win BB.
