(Warning: the linked picture is very, very big. But it's got ever so much detail.)
Remember how the judges always split when it came to the bottom two each week - except, crucially, when Olly met Jedward?
Turns out that that was what saved their beaten finalist. ITV released the voting tallies on Sunday night – here they are, in a PDF – and the figures show that while Danyl had a very up and down time, and Joe just got better and better, if the judges hadn't saved Olly on week seven, over Jedward who actually had the bigger public vote, John and Edward might have been in the final.
Jedward in the X Factor final? Stranger things have.. actually, no, they haven't.
