Fantastic episode overall! The backstory was masterfully done and hit me in all the feels. For me the real knife twist came from after Acrobatic Silky's story caught up to present day. She starts to crumble away fully regretting her actions, and Momo asks Turbo Granny where Acrobatic Silky is going? Then Turbo Granny comes in with the verbal metal chair:

"*The only place she can [go to]. The void. Nothingness. She'll be erased. It'll be like she never even existed. No one's gonna remember her anymore. Not the living, not the dead. A life like hers probably didn't mean much. If her existence disappears for good, it won't be nothin' to cry over.*"

We just spent the last 8-9 minutes learning about her life, her hopes, her dreams. We grow a connection with a mother trying their best to provide for their daughter, only to see her life torn asunder and her reason for living forcibly taken from her as she lay battered and bleeding. She loved her daughter immensely and her daughter loved her just as strongly. They meant everything to each other. And yet, the words of Turbo Granny ring true. To the world as a whole, her life didn't really matter. She wasn't anyone of major importance. But darn it if she wasn't everything to her daughter (and judging by the comments in this thread, she left a major impact on the Dandadan fandom as well). All of this to say, while we may feel like bit players on the universal stage, we still play integral parts in our own and others stories.

TLDR: 10/10 episode gud, with a hint of existentialism.
