Cullen gets the note Mei left him translated.. It's an address, her address in China.. at the missionary in Ningbo... He gets offered a job with the army.. he takes it.. then realizes he made a mistake... he goes to a church, confessional.. just sits there and says nothing while the priest asks him questions.. then he has some type of epiphany in the booth and starts laughing / crying..
back at his hotel room.. you see him getting ready to leave as Durants speech can be heard.. they show eva too who rides off to somewhere on her horse... a shot of his army uniform left on his bed as he leaves.. next they show him on a train.. a guy comes around and says next stop San Francisco.. they show him arriving at the passage to china ship yard... show him holding Mei's note while looking out over the ocean.. then show the hull of a ship... then show him on the ship off to China..
