I know this is not a popular opinion around here but, I feel so sorry for Dorothy. Niles, being an idiot, neglected her her entire life, did not even know she existed until he accidentally found her while she was being cruelly exploited as a sideshow freak, then he kept her prisoner, not allowing her any sort of life for almost 100 YEARS! Not once did he try to understand the culture her mother came from, not once did he talk to her about how she came to be in that sideshow, not once did he go back to see her mother before mother died. Not once did Niles try to really get to know and understand this little hybrid being that was his daughter. Niles is a horrible, horrible person, as bad as Reginald Hargreeves + Lionel Luthor. The child had no idea she was having her period and that alone made me so angry with effing Niles. That whole "Dorothy's special day" was INFURIATING. Instead of giving her this silly, empty day of "fun", he should have been talking to her straight, explaining what he understood of her true nature and together, perhaps they could have come up with a plan to deal with that wax demon thing. Instead, we get another avoidable catastrophe. Personally, Im really fed up with men refusing to take responsibility and relying on magical thinking + a strong wishbone to "solve" problems. I just really, really feel sorry for Dorothy, she deserved better. Hell, that asshole Cliff would have been better.
Now in other story lines, we have Jane and the Underground. With one episode left (which we already know is an unintended cliff hanger), I'm not seeing how her story line is really going to mesh with Dorothy's. There was that one brief overlap with the wax demon thing going into the Underground (somehow) and killing (again, how?) 2 of the alt's but beyond that, this story line is not even working as a commentary on the main story line with Dorothy, at least not for me. OK sure, Dorothy's father ruined her and Kate's father ruined her but the parallels are just not really working. I mean, ok, this season is about failed fathers: Cliff trying to reconnect. Niles using magical thinking and neglect as crutches. Larry reckoning with the damage he inadvertently did to his family. Overall though, the Underground story line just feels so unconnected....eff it, the entire season feels unconnected and not at all as satisfying as last season.
Last thing, I love Dorothy and wish one human being was really, HONESTLY looking out for HER best interests.
