My entry. It started off kinda cool, but it took a dark turn because I was listening to music that reminded me of Viper's backstory. Yowch. Explanation on this below
Credit to @Skorch for the CC So, this is obviously after Viper ran off from ShadeClan. What happened was, after the warriors of ShadeClan ran off to do battle with MistClan ((these are Clans from the rp I had with my friends a long time ago)) Viper slipped into the camp and found her half-sister's kits in the nursery ((Half-sister story is for another time.)) and being cold and dead inside as she was, she felt the need for revenge. She murdered Moonshadow's kits and then confronted her. After about an hour of heated quarreling and skirmishing, Moonshadow called her a human swear word. So Viper ended up killing her half-sister too, and that is the fast version of how that went down.
