Surely a harness is what you put on a horse when you're hitching it up to pull a cart or carriage?
Anyway, whatever the terminology, I reckon that was staged by Rob, because he knew that hunting might trigger Shula's memories of the hunt sab, so he had to be seen as the hero. Nonetheless, with 9 million years of horsehandling or whatever she's got, i.e. a lot more than Rob, it wasn't credible, as has been pointed out.
And Helen's still trying for Ian, because she hopes Ian will realise it wasn't her fault at all, it's all Rob, and Ian will save her.
I'm a Phoebe fan, too, and as much as I'd like Jenny to be brought down a peg or two by Phoebe getting a rejection from Oxford, I don't want it enough to sacrifice Phoebe's future.
Did Debbie ever actually graduate, or did she get drop out because of shagging Simon whatsisface?
