Cowell saw an opportunity to get more money from votes
Plus he will have headlines about bringing back acts voted off weeks ago instead of bringing back the likes of Sami or johnny
Imagine the outcry now should Amelia get voted back and then win
Cowell is rubbing his hands at the headlines he is getting now, they have been clever also in the ones they chose knowing there is only really one stand out act in there.
I feel for the other acts, but it was inevitable that this show being more about the judges and headlines rather than the singing was going to add more twists
At least it will liven up saturdays show seeing as the last few have been forgettable
