Note: Full spoilers for the episode follow. The Sisters of Mercy stronghold, which caters to only women and children, appears to be a welcome temporary safe haven for the group to recover, gather some food, and prepare for their continued trek towards California. However, as we’ve seen in most apocalyptic adventure tales, most safe havens tend to have a dark side and this is no exception. Addy’s unstable emotional statement following her rediscovery of some unsettling repressed memories a few weeks ago are the cornerstone for what transpires this week.
