Inception

[blackmage_nuke]

Well I cant say for certain but I dont think it's ever declared whether being an extractor is legal (I assume not unless he's extracting for the government) If he was an extractor before hand no doubt he would have had to get used to covert operations since it involves a lot traveling and secrecy, being good at being on the run wouldnt be a big leap from there. And even if he were doing it legally most of the time he'd have to hide his identity from his targets so I can imagine he already has the fake identities and con artist thing going. Also since he fled the country I dont think America would be trying to track him all over the world over one murder of for all they know was probably just a normal housewife, unless they were both government workers, i get a strange feeling they were but everything is starting to get hazy so i dont know.

Also its hard to say whether the kids moved in with their grandmother or their grandmother moved in with the kids (or maybe everyone was already living together) But if it was the former, would it be so hard to imagine that coming back home after months that the kids would go back to their favourite play spot? Like Cobb said, his son was digging for something, maybe he burried something there and wanted to see if it was still there?
