I quite like Mike too! Definitely grown on me. There's an arrogance and superiority there, that when it comes out would make you want to wring his neck BUT I don't think he's sinister. If anything I think Heidi could influence that side of him.
I also believed him when he said he loves her! His family pointed out how many good things he'd said about Heidi, which we never saw but clearly happened. The negative waffle in the vows was done by all the others who'd had far more straightforward ixperiment so it goes with the territory, surely? Producers probably wrote it for him!
I thought it was telling how Heidi couldn't stop saying how much she loved him - she's obviously been dying to say it for ages and wishing he would. Explains a lot.
That said I think it'll end. They're just not suited. I'd put money on them not being a couple now!
Cannot WAIT for the next dinner party!
