When Spike and Twilight get into a fight with one another and Spike storms out, the town goes on a search party looking for the baby dragon. After days and no sign of Spike, Rainbow returns with an injury that could only have been inflicted by none other than Spike.
Realizing the futility in Twilight or her friends reasoning with Spike, Sombra takes it upon himself to find out why Spike was so upset in the first place.
Sombra could never have been prepared for the answer Spike was going to give him.
Side story to my multi-chapter SombraPie fic. SombraPie is included in this story, but to a minimal amount.
