kinda shows why Dylan chose to only spend a few days of the Christmas holiday at home! probably couldn't stand the thought of being stuck with her for the full three or four week holiday - especially without his own bedroom, because she's converted it into a playroom thus he is expected to sleep on a sofa bed like a visitor to his own home
- but also the control of being told he isn't allowed a snack or has to ask permission to eat certain foods etc. Dylan will have got used to the freedom he has at uni, having escaped Rhi's control, and i doubt he would willing choose to spend weeks with her dominating and bossy personality when he doesn't have to!
it's sad, because kids at uni generally go home for the holidays, and spend the full however many weeks back at home, yet poor Dylan has been made to feel his family home is no longer his home, because Rhi perceived his very first term at uni as him "moving out", so he doesn't feel welcome or comfortable to spend more than a few days staying there. sad for Dylan, but also sad for the younger kids who obviously have a close relationship with their older sibling - especially Will, who is often ignored by Rhi because the focus is always on the girls. such a messed up family dynamic, and all due to Rhi's dominating and controlling nature.
