Vote to evict + weak characters make it hard to predict a winner
 

Lots of the popular characters featured on HL show with larger fanbases eg Gina, Dan, and Dexter will be up for eviction as they are big characters who cause conflict and in a VTE could be evicted over a dull character whereas they would have stayed in a VTS. Gina would definitely be evicted over Sam, Sophie or Daley i think.

Although the duller / weaker characters such as the twins, Wolfy, Sam, Daley, Jackie Sophie will be less likely to be nominated any time soon they get less air time and aren't doing enough to justify a win come the final.

In other words, it will be tough for Gina and Dexter (or even Dan) to cling on till the final as it's vote to evict, but if they stay till the final week and the dynamics don't change too much (eg Sam becomes a fascinating must see character and Daley turns into Dr Evil, Sophie becomes witty and hilarious) Gina and Dexter could both easily walk the final (providing one or the other is evicted)
