Brian is the one who doesn’t mind taking orders from the group and would just love to be accepted by them all which is why he usually opens his mouth to comment on or agree with whatever is being said, but sadly he usually shut down only to be embarrassed by another one of John’s inappropriate comments. This makes him the most affectionate. He is very open to expressing his feelings and doesn’t even hesitate before opening himself to the group. Claire and Andrew are less open since they aren’t used to being intimate with their group. They usually just go with what everyone else is doing and John even picks on Andrew for the fact that all he knows how to do is take orders and he is unable to think for himself. Alison is not very affectionate because she is ignored by her family and probably has had many negative experiences when trying to express herself to them so she either stays quiet or makes up outrageous stories to get shock the people around her and possible get them to hate her or think she is a freak. John only opens himself up when he is trying to prove to the group that his life is the hardest of them all such as when he describes how he is yelled at and beaten by his father.
Cohesion is basically the unity of the group and how well it sticks together and supports its members. In the beginning, the breakfast club was fighting against cohesion. All the members (except Brian) wanted nothing to do with one another
