But why is he back? And what does he want?

Harriet is moved when Dawn wants her to be her maid of honour, but they still need a venue.
With Kim a little unenthusiastic about Dawn’s wedding date news, Will emboldens her to find something that will put the spring in her step again. So she offers Dawn Home Farm as a wedding venue, leaving Dawn thrilled.

However, her excitement is halted by the return of her ex, Alex, who pleads with her to let him explain his previous actions. But what else does he want?

Apologising for missing Dawn’s hen do, Kim heads off to the auction, dressed to the nines and we later see her on the phone with a smug look on her face. She’s clearly purchased something profitable. And later, her news affects the villagers.
