Just re-watched Par Avion. Sorry if this has already been brought up a hundred times previously! So if Claire's Mum was being kept alive by the machines, how come she was ok to go to Christian's funeral and then later to look after Aaron? My first thoughts were a) was she miraculously recovered? b)was the person claiming to be her an imposter? or c)was it some sort of alternate timeline? I looked at the Carole Littleton article and on the theories page there were some good thoughts about Carole being healed by Jacob (perhaps in exchange for Claire staying on the island) and also the idea that she is not really Carole but maybe an imposter working for Ben or Widmore. (If so, then who has Aaron now?) Maybe an alternate timeline could be explained. What if the truck driver is someone we know? Any thoughts?
