[spoilers] Harry and Ruth Strike Back

[Tea Lady]

Having just watched 2.08 I think Harry had decided to make Ruth permanent before she confronted him about it, but for some reason he couldnt tell her yet. It was just the way he had his hand on his head and couldnt look at her when she was yelling at him a little, in his office. He was obviously feeling hot under the collar about it all and a little uncomfortable as he had to shift his neck in his shirt to compose himself just like in 8.8 when Ruth confronted Harry again about the Home Secretary.

As to when they fell in love I think it was between 2.05 and 2.10. I think for Ruth, it possibly was the EERIE exercise and for Harry, well perhaps it was the EERIE exercise and the thought of losing her to GCHQ. I think their love grew from genuine fondness to love over that period. By the third series I think they both are in love with each other and it grows even more over the next two series.
