Whilst it has been interesting, a lot hasn't really made sense about the whole sir Dennis story.
Did Jac approach him, did he approach her or did he just see the job advertised and apply in the standard way. How much influence would jac really have had? She was, i assume on the interviewing poanel but had clearly declared that she knew him so perhaps could be thought to have a vested interest as his having trained her was included on the press statement when he was appointed. Even if she was going to vote for him no matter what, there will have been at least 2 other people on the panel, probably more, including Hansenn so his back connection to jac should almost have become irrelevant. Why weren't references checked? Why did nobody know he hadn't operated fcor 5 years and that his mortality rates had been so poor in his last 'shop floor' role. Those stats are a matter of public record! Hansenn gives the impression of knowing everybody that is anybody in the medical world let alone somebody that was such a pioneer he has had operations named after him and fellows are writing papers about him as Mo said she had. Why didn't Hansenn know before this? Is he racist and why had that never been noticed before? Why did it not prove relevent in his downfall or are we supposed to believe that he was so reticent about operating and encouraged the DNR because Ina is black?
Going back further into Jac's story, the Byrnes, also CT pioneers, in fact pretty much presented as gods in the CT surgical and old boys network world didn't know Sir Dennis Hopkins-Clark and his guidance of Jac? Why did she even need Charles Byrne if she had somebody as influential as Sir Dennis in her corner? This was 10 years ago remember, before he is supposed to have 'lost his touch'.
Yes, jesse's farewell to Jac and her reaction to it would have been funny and humanizing if there was any background to it. If it was somebody like Spence, Ric or even mo who she has had an up and down relationship with (sometimes good working relationship and borderline friends but sometimes almost all out war) it would be a good final pay off but coming from somebody who she has never shafted, who she has in fact helped (employing him in Darwin against Guy's wishes when he was still CEO so powerful and he and Jac were allies so it could have cost her) just seems churlish and ungrateful. Similar to Bernie's crack about Jac not being able to order Mo around as the best reason to become a consultant when hac hadn't done anything to Bernie except advise her there was a job going, recommend her for it and compliment her in theatre.
It does just smack of every character having a 'right' to bitch about jac because she is such a horrible person, even if Jac has done nothing to them and they haven't even witnessed her shafting anybody else.
