Re: SSR ... SHIELD ...strategic homel ... wait
Since 'SHIELD' at that point was unknown to the general populace, I think Coulson used the entire name to sound more official to Pepper and Tony. Say 'Strategic Homeland...' and I'm thinking "Govt". Say 'SHIELD' and I'm thinking "huh? Bugger off".
Favourite? Superman by far. If he's off saving another planet, then Thor.
Immature and irrational dislike of Batman, Wolverine and Spiderman purely because of their popularity.
