Is Matt right about the price of the acreage?
No idea, but I suspect Justin's initial offer would be less than it's worth, and also that Matt would pay more to get back at Justin. Bridge Farm shouldn't trust either of them, but at least it might trigger them into thinking about valuations and so on, rather than just going with the first offer.
Of course, Tom has already phoned Justin to say they want to go ahead, so there's not going to be any awkwardness there.
And somewhere down the line, we'll have Tom realising Kirsty was right about him and businessmen, and he'll forget his promise and ask her to marry him again, but it'll be way too late, because Kirsty will be running an organic bee empire with Patrick and be president of both the WI and Borsetshire Wildlife Trust. Kirsty and Patrick will have normal, well-adjusted children, from whom there won't be any sound until they're 21 or older.
