I am totally not surprised by the engagement.
Khillip came, talked his skinny ass into her bed by agreeing with everything she said (remember the 'I agree' comments he made in the beginning?)
Then he isolated her, removed everyone (Marie W, MPK, Cat, baghead, potts,selmar) Marie W is now back because seeing the same 3 persons day in day out is quite boring. SJ is boring, because she is lying in bed doing nothing.
I do believe they have an agreement on sex. They can share the bed with whoever they want.
So what's in it for Hairbal? He has no qualification where he might make a good living off. A degree in theater isn't going to pay for 99% of the people. In the Netherlands he'd be lucky if he could find a job which makes him 2K a month for 40 hours a week. Attaching him to SJ, he gets to travel in style all over the world and live in a chateau (which I do believe is his passion) while doing 0 work.
What's in it for SJ?
She has never ever taken a decision in her life and she can't make decissions. She happily leaves that to tripod Phillip (which he likes), and the only thing she does is picking out which wallpaper what fabric, cornice, door etc. She'll have a travel partner, a 'planner', a lady in waiting.
It's a win-win.
Now this hairbal gives me icks from the start. Since he now has more foot on the ground in 'our chateau'. We will probably see him making more decisions and go aheads for works. Interesting times.
