Sawyer's dad did kill the mom. What had happened (as best as I can remember) is that this guy (the real Sawyer) swindled "island Sawyer's" parents. The dad got distraught when he realized what was going on (I think mommy was doing the same thing with "real Sawyer" that our Sawyer was doing with the last woman we saw him with before the crash. I believe she was sleeping with him or something). Anyway, the father broke down the door to the house. Mommy hid our Sawyer under the bed and from there, he could hear mommy and daddy arguing. Daddy shoots mommy dead and then walks into the bedroom where little James (island Sawyer) is hiding (but daddy doesn't know that) and kills himself. island Sawyer looks like he was only about 6 or so when this happened so he's been hunting down the real Sawyer for years. Talk about holding a grudge. Sawyer's probably about 36 or so? I mean, Josh Holloway's going to be 37 in July so I can only assume that the actor ages match the character ages. So, if "island Sawyer" was 7 when mommy and daddy were swindled and subsequently died, that means he's been holding this grudge and planning this vendetta of his for 20 years. I say forget the vendetta. By now the guy who did it is most likely dead anyway so let it go. Get on with your life. Get some lovin' from Kate and get over the past.
