    Summary

    Here, (not for the first time,) romance takes a backseat, and the constant suffering of one skeleton continues. Aka,

    Literally everyone except for Razz and Blossom thinks Comic's cheating/about to break up with Blue and Red. They've got it all mish-mashed. The skeleton needs a hug. And for his magic to be restrained to an extent. (Don't look at me like that! It's true. He needs to take care of himself before he does something stupid! - Too late for that.) Aka,

    Comic stretches, snaps and tries to kill himself. No one is happy about this. Aka,

    The Author tries her hand at suffering, suffering and more suffering.
