Last week’s episode had a lot of action, a lot of conflict, a sense of humor, and some character development. In other words, this series is finding its footing, and its way, in Season 2, and tonight there’s a major confrontation regarding the secrets hidden within the subterranean mystery city. It’s a mystery that, tonight, leads to some solutions, some showdowns – and to our first TV glimpse of a particular alien race from the Marvel universe.
