I mean a real angel. A soldier of the Lord. Some do choose to do good acts while posed as humans, so I suppose it is possible you could meet one without knowing.

But I -- [He stops and sighs, dragging a hand over his face.] I was an angel. A soldier of the Lord, sent to Earth to try and stop Lucifer from walking free.

And I failed. We failed, Heaven failed. And once we did, my brothers and sisters started leaving Heaven. With no angels left in Heaven, I became mortal. Human. And I chose a lifestyle as unangelic as I could imagine, so I didn't have to think about the days when I used to be an angel.
