My mate here thinks Clare's son is the smoke monster, which would make the smoke monster Jack's nephew, while I think the smoke monster is the island itself and in any case Hugo kicks arse and Jack and Kate (even though she's hot as, and then some) are so bland I'm glad they ain't having any lead role for now. I wish Sawyer had a more prominent role as he's always been the best character, with Locke, for me in the series.
And am still wondering, as the black dude reappeared last night, what happened with his son; loadsa fuss was made at the beginning about him and his superpowers. Methinks that's going to be a loose end in the series.
