Torchwood

Sound
During the dance the music is feminine when the men and women are dancing together, and it then changes when the two gay men start to dance, this shows how they don't care what anybody else thinks and that they love each other.
At this point another man says: 'what's he doing?' this shows that he doesn't agree with his friends sexuality and he is confused at why he is dancing with another man and not a woman.
There was a loud bang which stopped the couple from dancing, this shows that not everybody is accepting of their sexuality and also it makes the audience feel disappointed because they wanted them to kiss and have their happy ending.
