Ash leaving would have a far bigger effect on the group, mainly because himself and his 'gang' are so insistent that he isn't leaving.. it would be a repeat of the whole Tamara eviction again, but on a bigger scale.

Toya leaving would perhaps come as a shock to Danielle/Ashleigh/Kim, but the other housemates wouldn't be too bothered I don't think, as they don't hold Toya in such a high regard as they do Ash.
