Yeah, good questions, Vihzel. It'll be interesting what happens, in alot of ways Lisa seems to want to go against her mother, whether she has plans or not she does seem very conflicted. I also wondered why Joshua was brought back. One thing that has crossed my mind is that Anna's second in command, Marcus, might not be completely loyal to Anna.
The surveillance issue bothered me too. For a race so advanced they can't seem to keep an eye on their own ships. Also, since they are so advanced and tapped into the humans communications, how can everyone in the fifth column be able to communicate via cell phones without the vistors knowing. Erica had a cell phone on the mothership and used it to excuse herself from the dinner, yet Anna didn't know if she really had a call or not? Anna seems so trusting of Erica, yet Marcus seems to know so much about Hobbes and even told Hobbes he has actually been working for them, so I assume the mysterious woman that Hobbes talks to is a visitor and he has told her everything about the people in the fifth column. So all that is what makes me question Marcus' loyalty to Anna or if he has another agenda.
I think there are some alliances being made that arent straightforward. Isn't necessary humans vs visitors, some people have their own self-interests in the alliances being made which always creates twists. There was some of the same in the original.
I guess we'll know more as the story unfolds. I agree the Tyler character is kind of annoying. That whole storyline is interesting, Anna seems to really focus on that and it appears to get closer to Erica. It is as if for Anna, everything hinges on Erica, but why? It is as if the key to domination of the human race hinges on an FBI field agent.
Anyway, I'll stop rambling, they have certainly gotten us to watch another season, that is for sure.
