I see it as destroying the status quo of the relationship. For example, you have a man that it totally dominating the relationship, telling his wife what she can and can't do, but he doesn't want his wife to tell him what to do. Maybe the wife, who refuse to divorce him, believes that she is in love with him, is tired of being her husband's doormat over the years. Then one day she snaps and can't take being told what to do and be controlled. She instead of being tolerant, she screams at him, cusses him out and threatens to divorce him, if he doesn't change his ways. She refuses to go with the status quo of the relationship by defying him.
Maybe he told her what foods she should cook for him every night, maybe one night she decides to stop allowing her self be treated like a cook at restaurant taking orders from a customer, but instead decides for the first time in her life fix a meal that she wants to eat that maybe he doesn't like.
Tower is a complete "F*ck you, I ain't taking this no more." in a relationship that has happened overnight out of the blue. Not a slowly change in a relationship. But a huge drastic change.
The change can be totally chaotic, since is so new all of the sudden. Again, out of the "blue".
