It's Casper isn't it with Emma who reminds him too much of his sister? I mean I can understand that, but there my understanding is struck down.
From what we saw of him, he hadn't got much body confidence having been bigger and possibly teased in his youth, or have I misremembered? He's felt over shadowed by his family and now he's looking for someone to love and be loved by, who will like a wholesome outdoor life with dogs and an Aga. Seems pretty straightforward so far. Emma comes along, educated, pleasant, pretty with lovely hair and then, low and behold he becomes a sulky body shamer with a really vehement attitude problem towards his sister.
I can understand. Perhaps twins' relationships can be as distant as they can be close and perhaps Emma is irritatingly loud or opinionated, although some of that may well be nerves and over compensating, who knows. It seems very odd though. I saw a clip of that podcast, don't want to give away what Emma said really, am sure the story will unfold as they all do. If he actually wanted someone who was his 'type' then he should have been open about his likes and dislikes.
The most unpleasant really so far seems to have been Charlie and Eve. Very immature, damaged and/or toxic, take your pic
