Take Ian and Jane for instance. For once we have a relationship involving Ian that did fall apart (over an affair, shock horror) but instead of Ian going on his regular vendictive streak or the woman trying to off him, they've gotten back together and are working to make a go of it! And I know Ian can be an absolute git, but he does have a good side. And I think Jane really is good for him. He has also been there for her in the past and supported her. They're a great combination.
I am so glad they did that
The problem is they don't have a lot of screen time at the moment. So it's like they're hiding the happy moments behind camera.
