How the heck was last night's Westworld supposed to top Bernard's batshit betrayal? If you were expecting another crazy twist this week, you were probably disappointed, but the episode did manage to pull off an impressive juggling act, inching all the major character plots along and setting up the potential for a chaotic robot uprising in the weeks to come.
