I have started re-watching the Doctor Who reboot. And in the first episode the Doctor and Rose hold hand like 10 times. They are complete strangers. Why on earth would she do that? My only thought at this point is this is a European or British thing. I spent a few months in Africa and they would randomly hold hands with people they just met but I did not hear this was the case in UK as well.
Alternatively are the writers trying to show The Doctor as someone people just trust?
Or perhaps just trying to suggest Rose's instant infatuation with him?
P.S. In case it wasn't obvious from my cultural ignorance I'm American and in America only people in a romantic relationship or pre-teen girls hold hands.
