I WAS THE ONE¬!
I chickened out when I got to 2000ms points but wanted to make sure I won something, had used 2 lifelines and know Im no Einstein of general knowledge!
Totally random too - had only joined the game just before the guy got disconnected and my avatar splashed up!!
If you ever get to be the one expect 100s of people asking you to join their party, be their friend, send voice messages and 2 or 3 people made it so that I continually got chat requests until I turned my xbox off and on again (after the game had fiished of course!) idiots!
