Thats the bit i thought was odd too, putting all 3 episodes out on the same night, i suppose it gets all the press out of the way in one go and then by next week the programme is old news? But then again like @GoodOnYa said channel 4 loves the controversy!
Also yes when someone starts IVF they usually ask if youve had social services or mh difficulties, i work in mh and i have had gps or clinics ask our service to provide information to confirm there are no concerns, if the priory really are involved at the moment then they will be aware of any safeguarding concerns or drug use and have a duty to inform IVF services who would most likely say no. She could still go abroad but social services would 100% be involved and i dont think her pride could take it if a child was removed from her care at birth, how would she spin that??
I wouldn’t worry too much though, all these options cost money and by the time she sells enough shite through OF’s she’ll be too old for it to work!
