Not sure I caught that myself. I kept wondering the whole time why he was in China. I guess we'll soon find out if he "took" her laptop to plant a virus that Samaritan will get or to find out what she was up to. Could be some interesting directions the show could take in the coming weeks.
This show is so great. You think you are watching one thing then they do the metaphoric Inception gong and they take you deeper down the rabbit hole. Love the scenes with number making a meta comment about Reece being a super-hero which is what many fans compare the show to. Then you get the awesome showdown between Dominic and Ellias which you think would have the biggest plot mover of the show. Yet there is still more as we see the first major counter-offensive Finch has taken against Samaritan.
