I don't see why some posters hate on Jake for encouraging the others to explore their options.
Yes, he is shit stirring but the others and especially Liam could just have said 'No, thank you, I am happy with xyz' which makes me wonder if the producers have had a word and instructed them to show some interest to keep the public guessing.
Although, I feel Liam is taking it a step too far. If I was Millie aside from the fact that he looks like he is about to pie her off, I would be massively pissed off because he basically cost them 50k with his behaviour.
