I wouldn't say 'Pete and Glyn' were best friends during the series as Glyn was closer to Imogen, Grace, Mikey and Jennie but other than that I agree with your point and think it's a very interesing observation. For some reason I don't see it playing a role this year though as very few of the housemates have seemed to make any deep connections/rivalries, if that makes sense?
