Summary
In the Prime and Mirror universes, Spock risks life and limb to rescue his captain, who is being held captive deep underground. These two versions of Spock go on parallel journeys, never intersecting, but each in their own way demonstrating the love between Kirk and Spock as a universal constant that transcends the many points of divergence between their respective realities.
Please note that the Mirror Universe version of this story contains graphic depictions of violence and powerplay which may be disturbing to some readers. If this is not your cup of tea, you can skip the first three chapters and go straight to the Prime Universe version, which is far fluffier and tamer.
Written for the Spirk in a Cave event and gifted to jelliedlimes because this was originally inspired by their prompt about “hiding injuries in the mirror universe” aka “a horse that doesn’t want to be put down.”
It started there, but then I wrote the same story in the prime universe and paired them together because I’m extra like that.
