[spoilers] Harry and Ruth

[Silktie]

So when did I personally notice a spark? Well, their first meeting to be honest. When Ruth says "Bugger the Home Office" Harry gets this little smile on his face, and replies "Hmm, if only..." And gives Ruth this look. I think he realised then that there was something different and appealing about her.
Another telling development for me is in 2.10 when Harry chooses to confide in Ruth about his concerns over Tom, and she immediately agrees to stand by him.
The first overt spark however, remains my favourite scene between them. It is the last scene in 3.9, when Harry tells her he didn't get the DG job, and she says she's glad. That whole scene, they're almost having eye sex the whole time. Ruth keeps looking at Harry even when Danny is talking, and Harry keeps looking at Ruth as he's replying to Danny. And to top it all off, that wonderful laugh of Harry's as he calls Ruth back when she's leaving, and she says she's not listening. Wonderful stuff.
