Trailer Research - Eastenders "Under his control?"

The trailer starts off by Peggy looking like she is happy and doing something she would always do. The music in the background is like from a music box. She spots Archie from the mirror and starts walking towards him. The set looks technological because the lights on the floor go on and robotic arms starts whirring and takes off a flower from her dress. She is not happy about it but she continues to walk towards Archie as if she is walking down the aisle in her wedding. It seems as though he is controlling the machines and that they are "editing" her the way he wants her to look. He makes her dress shorter and replaces her tiara with a simpler minimalist tiara. Towards the end she is sprayed with something on her face making her face look younger. It looks as if he is in a mid-life crisis and wants something new in his life, a change. They are both quite old and they are surrounded by technology.

There isn't much to this trailer in terms of characters and speaking. There are only two characters and no one speaks, the background is very simple and not presenting the set of EastEnders. 

The main aim of this trailer is to attract their audience through their story line and through enigmatic shots. Why is he doing that? Why did her pupils go smaller?
