Length of service establishing seniority? I have no idea how rank works in the police.
Do we know why/when Rona (Rhona?) left? I've been rewatching old episodes and hadn't realised she'd gone away for a while, been replaced by the intensely-staring Asian woman with the bun who always seemed to have a slightly edgy/'off' relationship with Jimmy, though to my memory nothing ever came of it, and then came back again? (I just remember Asian Bun Fiscal walking out with her box of belongings when she left and Jimmy being kind of weird and just saying 'Good luck' and no one else volunteering anything. Did they actually have a huge clash and I've forgotten? Their interactions always just looked like there was Unspoken Tension that was never actually clarified...)
Are we to assume that after Jimmy let the American guy go free despite an extradition warrant being in the pipeline at the end of the last season, Rhona also got into hot water and was fired/moved?
Agree that Harry seems a bit of a bleaty damp squib in a suit. Rhona would have been interesting for someone like Ruth to bounce off. She'd have torn strips off her.
I think the thing that surprised me most about the finale was Kieran going from Wet Lettuce to Murderous Strangler within about two seconds, even if Ellen was shouting unpleasant things at him.
I think one of the oddities of the writing of this episode was always, for me, Ellen's characterisation. So much of it happened 'offstage', in that she was already dead, and we kept being told about her by other people, or having her motivations (Petty criminal in a really nasty red dress in London! Pagan! Rebel! friend of the unfairly-treated Knoxes! Sensitive and upset by child's death! Inpatient at Suspicious Dr Whatsit's Clinic! So rude to the bus driver after her money was stolen she was thrown off the bus!) speculated about.
By the time she reappeared at the Bains' farm in the flashback at the end of the final episode to see Rory (or was he RuaidhrÃ?), I'd completely forgotten why she was injured, and had forgotten the two hitmen completely.
But I was actually inclined to agree with Evil Bain Matriarch that Ellen was trouble, which I'm not sure was the intended effect. Mind you, her biological father looked like he was born to play villains...
Bobby was being a bit mad giving the money to Tom Knox, surely, even if kindly meant? If it's criminal cash, it's perfectly possible there'll be an alert when the notes start being used, and the Shetland police are well aware there's a stash of money about unaccounted for, if a very poor teenager with a very ill mother starts flashing the cash?
Also, has anyone said where Jimmy is supposed to have gone with Meg? Is Cassie still running Duncan's wine bar? Could Ruth sublet Jimmy's house? I kind of miss it.
