Snape the spy [Harry Potter] by @andrpete (Andrea L. Peterson)

Guess who my favorite Harry Potter character is. Go on, guess.

...Anyway, minor spoilers for HP Book 4; but the only one who hasn't read that yet is my mother. This is Snape in his early twenties, being a you-know-what. I realized as I was drawing it that the Dark Mark is on the wrong arm, but I didn't feel like redrawing everything, so... er... just pretend it's the right arm, won't you? ^^;;;
