Parallels are fun, lets talk about Poppy and Lily's
Both are human like femenine dolls named and themed after flowers: Red poppies and purple lilies. Fun fact both of these flowers share a lot of simbolism with their characters.
Red poppies are associated with death, rest, resilience after loss, longing and separation, remembrance for fallen soldiers and symbolize hope that grows from horror.
Purple lilies are associated with royalty and status or quiet luxury, elegance and grace, success or accomplishment, high self worth, admiration and respect, creativity and individuality.
Both were placed in isolation by the Prototype by nearly a decade in doll like enviroments.
Both were brought to life through unorthodox methods and were the eventual undoing of their parents one way or another-Poppy was Elliot's world and losing his daughter broke him which led to his experiments in order to bring her back while Lily's existance was a karmic punishment for Gracie's conditioning. Both reaped what they showed.
Both are unaware that their parental figures, Elliot and Gracie, weren't that great people and have a rather innocent view of them because that's all they know of these people. Lily was lobotomized into forgetting her crimes as Gracie while Poppy was kept in the dark about what Elliot did in the shadows.
They feel they have to carry their legacy how their parents did it even if these alienate them from other toys: Lily by always carrying Gracie's teachings about good toys and Poppy by trying her best to provide protection as a leader to Safe Haven even if it means carrying massive guilt over the BBI.
They are held accountable by people, Harley and Oliver, for their parents's sins as they project onto them because since they are dead they have no one else to blame it all on even if they weren't alive at the time these acts were commited.
They take away our freedom for needing us to aid in their plans and also for being the first person they have interacted with since their imprisonment and due to being desperate (one to end their collective suffering and the other to end her loneliness), seeing us in a good light: An angel and a good toy.
They have some princess simbolism to them: Lily by having a princess dress cutout and Poppy by her design and her being the damsel in disstress we have to break out of her imprisonment (3 times soon to be 4) and more importantly both are the closest to royalty in the factory by being the daughters of Playtime Co's staff-Poppy having been adopted by Ludwig as a baby and Lily by having Gracie's guts and voice inside her.
They were both created by a Ludwig member-Elliot and Oliver.
Both had to live with the remains of their parental figures for a while until they were discovered by Leith and us.
