His guardian angel

"Hello Mathew! I'm so happy to talk to yooooou!" says a voice from Matt's shoulder. Turning to his right, a tiny angel fluttered there. Before Matt can reply, the angel started speaking again.
"Now I know you're confused, but give me a moment and I can explain. Every human has a little angelic in them and a little demonic in them, its what makes you so special. But when you touched that discarded arch-angel feather, your angel side got super-charged. So be careful with that power now. It won't last forever. I'm the embodiment of your angel side, I can't doooooo anything other than help you though, maybe flare up your power here or there, but nothing big. You though, you've got a lot of potential to do some good here." the tiny angel continued. Her (assuming angels even had genders) voice reverberated pleasantly in his head. In a deep gut way he already knew what she was saying, but hearing it aloud helped.
Matt and his angel sat quietly for a moment when the bus pulled up.
