hi! no need to be sorry, i’m pretty sure inception confused everyone so it’s okay :) from what i’ve got, the inception was successful & the team made robert believe that he was never a disappointment to his father, who didn’t want his son to follow in his footsteps, thus encouraged him to dissolve the company and pursue his own career. robert’s not angry because the team made sure that he wouldn’t be (earlier in the movie eames suggests to use robert’s anger but cobb says that positive emotion is always better than negative to perform inception). i admit that his conversation with eames-as-browning about “being his own man” is a bit ambiguous but i’d say it means he’s going to do what the team wanted.
thank you love! :D
