I think Bernard's suicide is meant to set up the eventual rebellion since Ford is in a weaker position now that his trusted right-hand man is offline. Either someone has to step forward (Elsie as a host?) to buttress Ford or he's going to have to deal with an android uprising and Delos' plot to oust him all by himself (he also has to explain to them why Bernard is now also dead). Something is definitely up with Elsie. Either Ford is buying time for her host to come online with those Ghost Warriors or he's cordoning off that area to protect his research but Elsie's trying to get Subbs' to rescue her by transmitting signals.
