we don't know if it's 100% happening because big brother has only asked for pairs to audition but have not said anything when revealing stuff.
But if it's happening what are your theories on how the pair thing will work?
Since it's apparently 40 days or something (

) i think the pairs will be a pair for a few weeks and will nominate and be evicted as pairs and 2 weeks before the final they will be as one. Only one person will win.
