IMO It can sometimes be a form of insecurity within oneself. If someone is laughing at another they are taking the heat off of themselves and they find it easier to ridicule someone else. Helen and Ash have not had any feelings for Pav before but they now need someone they can feel is on their side instead of the 6 uniting. Pav is dim to laugh at it and to join in with them. I have no doubt that once he has served his purpose he will be dropped like a ton of bricks.
