I think they dated for a reason and did help each other grow (he helped he to be less insecure and see herself a different way, whilst she grounded him a bit more and made him want to change) but I don't think they would've worked at all long term.
I know they kind of left things open-ended yet on good terms between them, but I like to think they didn't get back together and just remained friends.
I know Kim is not well liked, but I can't understand what she even saw in Max to begin with? She was shown as being quite cautious in relationships (given how long it took her to be with Andrew and how she gave him a hard time about being a posh private school boy at first). Her just jumping straight into something with someone she barely knew felt kind of OOC - like they needed a member of staff to disagree with Rachel/side with Max and she was the only one available.
I wish she'd just left with Andrew at the end of s4. At least then she would've left on a more positive note (even if the Grace stuff would've clouded things somewhat).
I'm rewatching s6 and just got to the part where Chesca tells the other teachers about the affair with Jonah. I love when Grantly turns to Ruby and says 'Take notes. Good research for your next novel 😉' whilst everyone else has a proper serious reaction. 😂
I know she's not the most likeable of characters, but I can't help but think how depressing her entire arc on the show is: Her partner leaves her for her best friend, she decides to have an abortion because he doesn't want the child at that point, they divorce and she attempts suicide, she tries to move on w/ Andrew who is hung up on Kim. Then she gets diagnosed with MS and has to deal with everyone feeling sorry for her, she's accidentally responsible for Izzy losing her baby and then decides to commit suicide due to fear of what might happen in the future.
It really feels like she doesn't get a moment of happiness and ends up just feeling like a plot device in Tom + Izzy's stories to keep them apart or put them back together.
Given what happened to both Tom and Izzy eventually anyway, I kind of wish Lorna had just accepted her diagnosis and used it as the push to finally travel Australia. She could've even taken up a teaching position out there and maybe found someone new. Maybe she still would've found it too much at some point, I don't know, but at least she would've got to do something she's always wanted first.
