Yeah, Lois found out years ago, but she didn't know for quite some time. I think BW started off strong, but variants (non-Loki related) have spooked audiences. I always thought Disney should have pushed it back further. I think Sam was right to hold back, but the Flag Smashers DID commit a lot of atrocities. And you're right, they weren't fleshed out enough. What's funny to me is that neither was the Winter Soldier!
