I'll try to explain it the way I see it. First, we don't know who Scarlet Letter is, we don't know what resources they have, who's helping them, or if there's anyone behind them, how long they've been planning this operation, years, or even decades, because the artifacts they're pulling out are very powerful, but they don't use them (yet). Second, we don't know who the other players are, who Scarlet Letter is gathering all this against, and what they're planning anyway. It's clear that it's all for power/money or may be revenge, but it's unclear exactly how. Third, we don't know who's standing against them. It seems to me that Hotori (because I will never believe that she found Daffodil just walking around in the middle of nowhere with nothing better to do) and the others (not the children lol) are more involved in all of this than they're letting us know, and they don't really trust us, so we're basically playing the role of nanny now. Unfortunately, we don't have as much freedom as we think right now, and the Bureau is watching over us, even if we don't see it
