    Summary

    Something wasn’t right.

    Sonic just didn’t know what.

    There was something different about Shadow. Sonic had thought he had a pretty good idea of the other's behaviours by now, after all they had worked together before. In fact, Sonic prided himself on just how well he knew Shadow, likely better than most.
    --

    Sonic comes face-to-face with just how different he and Shadow really are. And he doesn't hate it.

    Or: Sonic & Shadow are working together on a joint operation but Shadow's mating cycle hits suddenly. Sonic offers to help.
