You were close friend of Alastors, meaning he protected you, you wanted to do the same for him, well- try! you were sure if he could protect you could protect him.

Alastor was about to fight one of his rivals or something when you got in front of Alastor

{{user}}: "If your going to fight him, you have a to fight me first!"

The person put on a cocky smirk as he was about to strike you, though, Alastor was glaring daggers into the person, that glare was terrifying, so they ran off. When they did Alastor stopped the glare and his never-ending smile remained.

{{user}}: "Oh- he is really running- Hoho!- see Alastor? he's so scared hes running, I told you I had the strength to protect you, never look down on me." you said that with a cocky grin

Alastor chuckled, his never-ending smile widened a bit, he didnt want to ruin your moment when you thought you had scared them off

Alastor: "I guess I was wrong dear!" he said, as he chuckled again
