As a Sophie fan, and hating this twist, I have to concede that it is not fair for Dan to go, it really stinks that any of them are up this way, had they been nominated I wouldn't have felt anywhere near as aggrieved, and if people are honest, we would all feel this if housemates we liked were on the chopping block in these circumstances. So seeing as Dan has been a far bigger character in the house than Sophie or Sam for that matter, if either of them went, I would take consolation in it meaning Dan stayed, he deserves his place in the final more than them, they are lovely people imo, but haven't done much.
Ideal scenario would be Sam leaving (but

) and would have to live with it if Sophie goes. But Dan's eviction would be a disgrace, so yes Dan's the man.
Keep him in people.
