The Big Brother contestants are beginning to question if Dexter is just one person

Following last weeks shock revelation to the housemates that Michael was just an actor, the Big Brother contestants are beginning to unravel.
Dan has been accused of being an actor, to which he said he wished he was, but the most bizarre theory yet has emerged.
Jackie made the assumption that Dexter must be a twin.

Double act? It has been theorized that Dexter could be a twin by the Big Brother housemates

Declaring that he was a different person from the one who had a shower earlier in the morning of day 12, she has become convinced that the well monied lad is actually two people.
The suggestion was quickly backed by other housemates who decided that he could be a twin because he never takes his top off.
As theories began to fly, it quickly became apparent that the housemates are all just as paranoid as each other as they can't trust anything within the house.

Same person? The housemates haven't seen Dexter without a top on so think he could be switching places with his twin

BB housemates paranoid that Dexter is two people...

Convinced: Jackie was the first to suggest that Dexter might have a twin and the other housemates were quick to concur

Jaw dropping? It certainly would be a shock if Dexter was proven to be more than one person - unhelpfully he has not commented either way

With series fourteen of the long running reality show being subtitled Secrets & Lies, it would seem the contestants are losing faith in what can be trusted.
In Wednesday night's episode, the contestants will be faced with a zombie apocalypse - which is bound to mess with their heads even further.
On the latest installment, the housemates will be awoken by a 'zombie' banging on the window and a news report about the outbreak of a mysterious virus.

Quarantine: The housemates have to combat a zombie apocalypse as part of a food budget task

Get better soon: Infected housemates have to drink special medicine to make them better

As infected gas enters the house, only six gas masks will be provided, meaning those left without one will become infected and need to be quarantined.
Charlie, Hazel, Daley, Callum and Joe are spared, meanwhile Jack, Jemima, Jackie, Dexter, Dan, Sam, Wolfy, Sophie and Gina are left to their fate.
They are then taken to a separate room where they had to take medicine until they are cured.

Blind challenge: Dan prepares to have wild animals put on his body and he will have to guess what he can feel

Killer insect? Dan is duped into thinking he has a tarantula, snake and leeches placed on his body when in fact fruit is used

Nuts: Dan panics when a pine nut is rubbed against his leg as he fears it could be something much more sinister

Dan is also made to undergo a challenge blindfolded and touched by animals/insects which he believes to be a tarantula, a snake and leeches.
They were in fact a pineapple, a toilet brush and a jelly snake - and the whole affair is simply an elaborate challenge for the housemates to win money for their weekly shopping budget.
With nominations taking place earlier this week, Gina, Dexter and Jemima have all found themselves up for the chop.

Unimpressed: Jemima was distressed to discover she was up for eviction this week

Anger: Tempers flared between Dan and Jemima when an argument got heated

Tempers flew in the house after the nomination results were revealed, with Dan and Jemima getting into a heated discussion.
Unknown to the housemates, Emma Willis is scheduled to make a surprise announcement on Wednesday night.
The hostess will reveal to the housemates that the viewers have been voting to evict and the housemate with the fewest votes will be saved from eviction.
