If Ed Harris' character was a host in the 'present' and not only well into the future, that would mean he was a host when he was around Maeve around three or so episodes ago, right? If that's the case, shouldn't she have been able to sense that he was a host since they were around each other for an extended amount of time? She even used her Professor X powers to get 'other' hosts to shoot him while he threatened her; why couldn't she have sensed that he was of her kind?
