Operation: Smile

Agent 3 had given up a lot help the New Squidbeak Splatoon, but never thought it would cost all the things that made the hero happy. Callie, Marie, and even the cap'n pitch in to do their best to make their star agent do one thing: smile. In doing so, however, all they seem to do is delay the inevitable. One-shot. (Takes place before Splatoon: A Fresh Spark, so spoilers ahead)
