“A violin is something the ship can’t print anew,” my mother finally tells me. “Which means that we could be introducing discrepancies in the repeating timeline, if and when it degrades or is damaged. Even if the violin is kept in ideal conditions between lifetimes, it’s hard to imagine soft spruce wood surviving these thousands of years.” “So some Ambroses at the end might not have a violin, and some will. What’s the big deal?” I ask.
It's a kink in the armor that maybe PrimeAmbrose kinda did think about because he actually is very smart let's be honest with ourselves.
