All good questions sir but am afraid I just don't have the answers - do even the writers of the show ?!?!

Have to say I am only watching now to see how it ends - have come this far. To be honest I just get annoyed now with the back stories and dragging main story

11) Finally, what was the point of that weird episode last series where a couple were buried alive after being bitten by paralysing spiders? They only featured in that single episode? What did it mean? Will they come back?
Have to say this is something I have really wondered - what was the point in that episode ? Crazy

Another thing that gets me is remember the bird that Hurley fell in love with . They revealed in a flashback that she was in same mental home as him then it was never mentioned again . Uhh why ?
