Was there anyone who added credence to Jeremy's claim, that he loved farming?
None of his actions post murders, suggest that this was true. I would accept that in his current position, farming must seem totally iddilic.
Has Jeremy ever said he "loved" farming? If he did maybe it was figuratively speaking. Like I might say I love Supervet when I what I really mean is I would love Prof Noel Fitzpatrick to shag me

Is there any evidence Jeremy hated farming? He wasn't just a farmer he was a director at the caravan park.
Yes I think Jeremy was interested in farming from a biological perspective in terms of crops. He did biology a level with this in mind and Colin said they both liked growing things and visited Kew Gardens together.
