I believe the whole spencer story. It sounds exactly like something he would do. I remember watching MIC and there was an episode were it was revealed he slept with a girl in the bed of his then girlfriend Louise while she was having her finals in Edinburgh. This tells me all I need to know about what kind of person he is.
And I also remember how he met this waitress while traveling with Lucy Watson (his then-gf) in Barcelona. And he slept with that waitress right away after Lucy had just left Barcelona
