to get the pregnant girl from Two Shoes out of the show?
They make a fortune from the phone vote, so why on earth would they forfeit that so they could alienate viewers by taking the decision away from them? AIBU to bet the girl told them she was pregnant, they said "Oh fuck we can't have her on the show, what if something happens to her, what are we going to do?" and they came up with this "twist" to get her out?
