From a reliable source on Betfair forum ........
"Pairs will be called to the diary room together and will have to come up with ONE name between them for nomination. The two people with most nominations will be up, TOGETHER WITH THEIR PARTNERS. Also, it seems LIKELY but not certain it will be a vote to save. They will NOT be aware that the partner of the person they nominate will also face the public vote"
Make of that what you will - seems feasible and if that is the scenario I think the 2 people with most nominations would be Dickie and either Susie or Michael, so therefore it would be Dickie/Pete v either Susie/Imogen or Michael/Spiral. If it is a vote to save, Pete/Dickie definitely safe.
