Skalrath is the sort of changeling that doesn't stop rolling. Every day, a new face, every night, a new mare to harvest love from. Platonic stuff, but it's a living and it lets him make quota for the hive.
But following the Canterlot Wedding, even he runs afoul of a hard landing... and a newly-made orphan. Unable to bring himself to kill or set loose the colt, he decides to exercise his family act and take a short holiday from the grind that is his work.
It's only a week off, it's not like he's going to take the mother's place permanently... right?
