When he spots the lift, Harry breaks out into a bright, easy-going smile. He has found the right place and he did do the right thing by approaching slowly and in public - it doesn't do to try and sneak up on Torchwood.

Once he's down inside the Hub and spotted Jack, he waves hello and looks around. It's a very different sort of place to the Ministry, but there's a similar feel in the air. It's a sense of purpose, but not the sort of noble, banner-waving, trumpets resounding, gilt-covered purpose that seems popular in the public facing facade of the Ministry, but the more hands-on kind that he prefers. Given the choice, Harry would rather work somewhere like this.
