You've got the old/last flame keeper lady, who was being drugged--she can hardly remember much about the generation that handed down intel, but she had a good amount of what seem like the facts. She knew about the BC and the likely that the water was being doped to limit their memories.
I still don't think they've been down in the Silo all that long...maybe 100-125 years?
I like that Meadows withheld pertinent info from Bernard, even in her dying moments. It will lead to his curiosity getting the better of him and repairing that hard drive. I still don't think he's the actual 'bad guy' and he's doing the best with what he's tasked with and just following the order playbook. He knew Meadows had an innate way of thinking past the order and predicting moves--instead of just reacting, like he is. It was ultimately too scary for him--despite 'loving' her. His overall slope is still too slippery and he's going to end up making more emotional calls that will make him the villain...and also likely make Juliet the unifying heroine. I think she still needs to see what is in Solo's vault, that will prove a lot of what the Founders setup and she can go back with that intel.
Also still kind of want to believe Solo isn't really alone...but they could just be messing with us?
