My husband noticed the comic correlation early on.
The newest episode of TV Guide had a reader write in theorizing that Ethan Rom may be Claire's grown up child trying to prevent himself from being born.
A writer also said that it's likely someone will get whacked this season...someone we're invested in.
I'll say this: both my husband and myself agree: if Locke gets whacked, we'll stop watching the show. He's mesmerizing and 90% of the reason we watch the show anymore.
