It can't be a double eviction, because the only two people up for eviction are Derek and Roberto. So they are the only ones who could go, and if they are going to evict them both, what would be the point of having a public vote? They had a double eviction in BB4, but that week, the three housemates with the most nominations faced the vote (and don't get me started on how both Fed and Jon were evicted and Cameron
was kept in). Grrr
