So far I am fast forwarding Walt/Michael's backstory (can't watch the bits where Michael has to give up Walt), and Locke's backstory (somewhere along the line they are going to have to explain how he ended up in a wheel chair). Now they hit us with this thing about the children from the tail end being taken by the Others! I think I am going to have to get DH to watch it in advance to find out whether it is OK to watch.
