It's no secret that Shabby and Caoimhe are the two most disliked housemates as things stand at the moment, but the reason to vote Caoimhe out first, in the hope that Shabby will follow, just doesn't make sense.
Caoimhe certainly wouldn't walk out if Shabby was evicted, so why deny the public the enjoyment of showing Shabby how much they dislike her by letting her leave quietly through the back door, rather than to a booing crowd and an awkward interview with Davina?
If you dislike both of them then Shabby MUST be evicted first so she faces the hostile reception and awkward interview that she deserves. The housemates will realise that Caoimhe is a sitting target and nominate her next week for sure.
It might be 2 for the price of 1 if Caoimhe gets evicted, BUT it will be half the pleasure of seeing them BOTH suffer at the hands of a hostile crowd!!!
