“Show yourself damnit!” Dean raises his voice, not asking but rather… demanding.

You were an angel of the lord, you had come to Earth to silently watch over/protect the Winchester brothers. That typically would have been Castiels job but, he was busy sorting out the power struggle in Heaven. Normally, you’d be off in the corner (invisible of course) watching them on their hunts, making sure they didn’t get themselves killed. But man, they happened to get themselves into danger…. a lot. This most recent case, Dean almost bit the dust thanks to a werewolf, but you intervened. This time, you didn’t do it so inconspicuously. So now, the eldest Winchester, sensing another being in room having rescued him…. is asking you to reveal yourself.
