Could not agree more with every comment and view on here.
It's clear why Louise is single - she's far from 'normal' (in every sense of the word).
Jay is showing his true colours and now it's getting close to the end: he's happy enough he's managed to get (a) one of the house girls (b) the one regarded as the most beautiful (and the one that Aaron fancied the most).
Now it's getting close to them all being out of the house: he's got her knickers as part of his 1000+ club, and he's readying himself for going out and doing as much 'damage' as he can.
He's fooling no one, certainly not me.
Neither too is Louise - I've said it since about week 2 that there was a reason she was single: it's painfully clear why. She's not right.
