Shocking family secrets unveiled in The Apothecary Diaries season 2 episode 20

The episode's most shocking revelation centers on Shisui's true identity as Loulan, the runaway concubine and daughter of Minister Shishou and Lady Shenmei. This twist recontextualizes previous episodes while explaining the complex motivations behind the village's activities.
When Lady Shenmei discovers Maomao and Kyou-u investigating the firearms warehouse, Loulan's quick thinking saves them from severe punishment by convincing her mother that Maomao possesses anti-aging secrets.
The deception that Maomao is actually thirty years old and has been experimenting with youth-preserving medicines demonstrates Loulan's strategic intelligence while protecting her newfound allies. The relocation to the northern mountain stronghold provides the backdrop for a crucial family history exposition.
Suirei's revelation about her relationship with Loulan unveils a tragic tale of political marriages, abandoned families, and systematic abuse. Minister Shishou's adoption into the main family, his engagement to Lady Shenmei, and her subsequent assignment as a palace concubine created the perfect storm for family destruction.
Lady Shenmei's discovery of Shishou's marriage to Suirei's mother led to years of vengeful treatment, including banishing them to servant status and denying Suirei even the family name "Shi."
