My goodness! Two Draco's is a bit greedy on Snape's part (isn't this Snarcoco?), but a very hot image. (Now I'm hoping that an artist will pick this up.)
Loved the picture of Harry banging his head on the icebox in surprise, and his confusion (all the way through), and naiveté - he really never did learn to occlude, did he? Of course Snape knew the moment he peered round the corner into the room! I loved the way he just casually slips “Oh, but I think it is, Potter.” into the conversation.
I suspect that they're going to have a lot of fun together...
