I left my slash goggles at home when viewing Inception. On second viewing (and reading a devastatingly epic fic), omg I see the Arthur/Eames. Second viewing, I was all "Cobb who? GTF off the screen!").
The other thing that struck me was how does one phonecall minutes/hours from landing to whomever to clear Cobb, translate to all pertinent people speedily getting the info that there is no problem with Cobb re-entering the states? Like, I don't doubt Saito's influence, but the speed at which it would trickle and update in all the pertinent databases.
"...and I'm really good at holding my pee!"
This would actually be a really helpful prerequisite for basic training where they make you drink lots of water but don't seem to understand the effects of such.
