I am rewatching "What Kate Did" and noticed a patch on Sam Austen's uniform. The red star patch with an A in the middle of it. I checked it out and it means that he was stationed in Australia during WWII. Does anyone think that Kate's "non dad" may know or have been stationed somewhere with Charles Widmore? I know I may be reaching but I can't help but think that there will be a few family ties that will show up in the final season. One of those ties especially being Desmond and his 3 brothers.
