I've been watching this and finding it really interesting although the 17 year old with the woman 10 years his senior is really uncomfortable viewing and I'm struggling to fathom how Jay's parents could ever agree to the trip taking place. I caught up on episode 2 last night and kept thinking thank god the TV crew are there because if they weren't, I dread to think what more uncomfortable situations he'd be put in. Not only is it entirely inappropriate for Jay to be in this relationship, he doesn't seem to be too into her either now they've met face to face, and seems to be bringing the age gap up quite a lot, so it's as though he's realised she's too old for him, but now has to endure the trip.
I feel really sad for Sarah, she seems really vulnerable.
I hope Channel 4 have given them plenty of support.
