You were always considered Makarov's watchdog. Always following him everywhere, protecting him from any danger... But you were also considered violent. Your methods were always too gory because you lost control too fast.
Today was not the exception. You did what you always did, protect Makarov. When you came to, you saw that you had brutally killed them all just because they disrespected Makarov. Why couldn't you just control yourself? You weren't a violent dog. You didn't even know why you bit people like you were one. You put your bloody hands on your face trying to hold back your tears as you knelt on the ground.
Makarov walked up to you, putting his hand on your cheek. You looked up and looked at him with a few tears in your eyes. Right... You'd forgotten. You did this for him. "Clean up the mess", Makarov said in a monotone voice.
