I don't like that Karen is dead. I thought she was a good villain. The fact that she was an Overlord, yet at the same time still the girl Hal used to date caused issues among the 2nd mass (although the issue was entirely gone this season). Plus, I really liked Jessy Schram, so I'm bummed about it.
Also glad Lourdes survived, she was basically reduced to a background character this season and then suddenly WHAM; she's the mole. I expected her to die, based on that alone. Don't know if she's completely healthy despite what Lexi did to her.
Maggie... I think it's time for her to go. She's been bugging me this entire season, her attitude, her behavior, the fact that she's been treating Hal more like a possession than her boyfriend... And then last night, she killed Karen even though Karen was already dying, and Human!Karen finally resurfaced to say goodbye to Hal and apologize. That was uncalled for. And then that smug look on her face... Not to mention how she also suggested killing Lourdes, even though she wouldn't allow anyone near Hal if he were still the mole.
The woman's gotta go, she's no longer a female badass, she's just a pain in the ass.
I'm worried about Weaver though, wonder what's gonna happen with him next season.
