Yeah, I was glad they managed to work out a system to keep New Eden going without Big Alice, I can understand Layton's desperation, but I would have hated to see him get everyone there killed.
It's nice to get a little more of idea of what exactly Milius is up to, and it's not looking good. I'm curious what's going on with Melanie that they seem to be avoiding showing her. Is Jennifer Conolly still in the credits? I didn't notice her name the last couple episodes.
I'm curious what exactly Milius's backstory is, I'm assuming since he's Admiral Milius that he must have been in the navy before everything froze.
The one big question mark for me that we saw in the trailers but haven't seen yet is Wilford. I'm curious which side of the conflict with Milius he's going to be on. Right now I see three possibilities once he shows up, it turns out he's the mastermind behind Milius's plan and they join forces, Milius is working against him and he joins forces to help the Snowpiercer people to stop Wilford, or the other way around and Wilford joins forces with them to stop Milius.
