A son for Kate and Sawyer. Interesting. But why would she leave a child in a house alone? Unless she's married to someone else now and he's at home with the child.
As an aside I had to share this with you guys. I had the strangest dream regarding LOST last night. In the dream, I was one of the survivors who made it off the island. I was in a big building waiting to speak with someone and I suddenly saw everyone going frantic and running towards one room. Everyone started embracing and I clearly saw Ekko. We found out that the whole time, the island was government run and that the deaths were faked. Everyone who was thought to be dead (Charlie, Ekko, AL, Libby, etc..) were secretly removed from the island and brought to this government facility. Is that the weirdest? Of course I don't think that's what's really going on but it was just so vivid I had to share it.
